I have been studying alot of ancient history, specifically ancient astronomy.
I am now certain that all world events can be predicted from studying the skies.
Anybody here using telescopes to photograph comets? I am looking for roughly what I need, and examples of what you guys are getting with your gear?
I really need to be able to see and photograph comets and meteors in space.

I photographed comet 12P/ Pons-Brooks on March 22nd from Norway. Captured right after sunset from a medium sized city (bortle 7 on the light pollution scale). This is around 70mins of exposure time in total.
If you don't know anything about astrophotography I'm going to warn you that it is a very expensive hobby and it takes a lot of time to learn how to use the equipment and process the images properly.

The gear I used for this photo:
Sky-watcher Esprit 80, Sky-watcher HEQ5 Pro, ZWO ASI1600MM Pro (monochromatic camera), ZWO Electronic filterwheel, Astronomik LRGB filters, Sky-watcher Evoguide 50ED + ZWO ASI120MM Mini for star guiding for the mount. Also have a lot of specific cables, USB hub and a PegasusAstro power-hub for power distribution. My whole setup is around 6-7k USD (in Norway).

I used a program called Pixinsight (280USD) for the stacking and image processing + some pluggins that were around (150USD). Again pretty expensive, but very fun and rewarding hobby at the same time.

Is this the astro thread? I have a question, I'm kinda new so forgive me if it's dumb. So far I only ever did milky way photography, with the classic rules of high enough ISO but not too much, max aperture or close to it, and 15 or 20sec of exposure depending of the focal length until it starts making trails. Okay, it gives good enough results, not great not terrible.
Then I stumbled onto "stacking" photos. If I get this right, I take a whole lot more of photos, and then stack them in software like Sequator or any equivalent. Meaning I can get less noise as I can use less high ISO. And I assume, I'm also get more light through stacking. Is that right?
My question is about numbers and equivalencies. Let's say we're using a full frame setup : 20mm f1.8 lens. Let's settle for 20sec of exposure at ISO 3200. And let's say I take a picture.
With stacking, how many pictures would I need to take to get the same picture taken above if I change the parameters to ISO 1600? Two pictures? Same question if I use ISO3200 but f2.8. 2 pictures as well? (as, unless I'm wrong, 2.8 gathers 2x less light than f1.8)? And then the combination of, I dunno, f3.5 at ISO 100. I assume I'll have to take 15 pictures or something.
Basically I'm trying to find the "conversion rate", if there's any. If so, stacking means I wouldn't have to buy an expensive wide angle fast lens, but could settle for wide but lest fast,, which is good for hiking. At the cost of staying there in the cold of the night more time that I would with a faster lens.

More is always better, but it has diminishing returns. For DSO stacking anything over 40 images is almost never worth it imo.

Like the other anon said: more is better. However keep in mind that the more frames you stack the more imperfections in the light path will be, so unwanted color gradients, dust particles on the lens, distortion and vignetting become very noticeable once you stack them.

So to get rid of these it's important to take calibration frames, flats in particular. Good vs bad flats can make a night and day difference.

If you want get into astro i suggest you take a look at this video, it goes fairly in depth and i found it very helpful starting out.

>There are common misconceptions regarding light gathering in photography. I'll first try and clarify light gathering by lenses as it impacts the choice of lenses for night photography.
>Photographers are trained that more light gathering means a faster f-ratio. After all, exposure is directly related to the f-ratio. But f-ratio tells light density in the focal plane, not total light received from the subject. Light gathering from the subject is actually proportional to lens aperture area times exposure time. What this means is that for greater impact with night sky photography, buy the largest aperture lens you can afford. This means the fastest f/ratio in a given focal length. Note, this does not contradict my statement about f/ratio above. For example, a 15 mm f/2.8 lens has an aperture diameter of 15/2.8 = 5.4 mm, an aperture which is smaller than the dark-adapted human eye. A 35 mm f/2.8 lens has an aperture diameter of 35/2.8 = 12.5 mm and collects over 5 times, (12.5/5.4)2 = 5.3, as much light from the subject even though the f-ratios are the same. A 35 mm f/1.4 has an aperture diameter of 35/1.4 = 25.0 mm and collects (25/5.4)2 = 21 times more light than a 15 mm f/2.8 lens. That would be a huge impact in light gathering in night photography when light levels are so low.
https://clarkvision.com/articles/characteristics-of-best-cameras-and-lenses-for-nightscape-astro-photography/

What the fuck, I mean it's obvious when you think about it purely on an optical and physical standpoint, but somehow it feels like everything I thought I knew was a lie, or rather, an oversimplification. I didn't think the light gathering difference would be so massive even when comparing at the same f stop number for different focal lenghts. It makes me rethink the need for ultra wide angle lenses for simple MW photography. Maybe a 24mm f1.8 or f1.4 is actually a better choice than, I dunno, a 16mm f2, at the cost of doing a stitching if I need to get a better composition.

>>
>>4328138
>I didn't think the light gathering difference would be so massive even when comparing at the same f stop number for different focal lenghts

It's a simple principle and the same idea behind equivalence. 16mm on m43 collects 1/4th the light as 32mm on FF (two stop difference). You can stitch 4 photos on a 32mm lens on m43 to get the same amount of light gathered on FF but honestly stitching is a pain and the stars are streaking and you've got to align that etc. Ignore Roger Clark and just get the fastest lens you can for the field of view you want. In fact, using aperture size is not all that useful for this application even though it is for general astro.
>>
>>4328138
Why does this not happen for me in normal photography? or is it a slight background light thing for deep space imaging, ie: longer lens sees more distant light
>>
>>4328138
Keep in mind the MW stretches across the whole sky. So you could use up to a 180° lens and the differences would be in how thick the band appears on the image.
>>
>>4328170
It does but Clark's thinking doesn't apply to normal photography. Think of using a 50mm for an upper body shot at f/4 and 1/200s. A 100mm lens at f/4 and 1/200s has the same intensity of light but in half the area. With the same exposure time, it's roughly the same number of photons being captured (assuming similar reflectivity for a subject). If you were to take two photos with the 100mm and stitch them together, you get twice the amount of light collected. This is basically impossible for subjects which are moving and stitching introduces a lot of complications (aligning focal node, extra distortion corrections, extra vignetting corrections) etc that make it a bad idea for normal photography. For astro, larger apertures collect more light for a given lens design but even then, stacking, sensor cooling, and tracking mounts with the right or wider field of view are preferable to stitching. Deep sky astro photographers will often image a faint nebula over several days and if they need it sooner, they buy bigger scopes.

For simple MW shots, stitching is dumb. Dunno if even stacking would be worth it but definitely more than stitching.

It looks better if you do a massive stack of thousands of frames from video, that way you can toss up the bad ones and keep only the cream. This process works on the square root of the number of exposures that you stack

The eternal question, getting a lightweight travel-hiking friendly small tracker like the recent Move Shot Move Nomad, or invest in pricey and weighty new lenses?
>in b4 "both"
It'll be one or the other, money is finite.
One one hand, a tracker offers lots of possibilities, though to be honest it's overkill as I don't intend to do any deep sky shit. Still, I wouldn't mind getting closer to the galactic core (like I dunno, at 50mm as they're cheap, or 85mm?), and maybe some big ass objects like Orion or Andromeda. Both will still need long fast lenses in the 135mm though.
Or buying faster lenses, both wide (stacking can get the job done though) and long. But even there it's overkill AND more costly. I honestly don't have any use for fastass lenses that need to be closed down a bit to be usable anyways. If I'm doing landscape, I close down anyway. And if I'm doing night cityscape shots, I'm on a tripod at long exposures. For muh borkah I don't need more than a regular 85mm f1.8, and it's already too much borkah for me anyways. Going faster on all my lenses would be a waste of money for my general photography.
There's no good solution, but like 250 bucks into the MSM Nomad could be the cheapest option, contrarily to what I thought at first.
>>
>>4332336
Hm. You couls buy Orion's 80mm refractor on their EQ-1B mount for $150 and add the motor for the mount for another $55 So for $250 (tax? Shipping?) you could have another tripod as ell as a small telescope and the clock drive.

Okay what the fuck, and did anybody on the planet check this formula out? Because I can tell you this doesn't make any sense. Even if I could see a star at f16, I won't get acceptable trails with 32 seconds. A dumb 200 or 300 rule or something makes more sense than this.

regular dude here. I thought it would be cool to try to photograph the perseids last year. I didn't want to spend a bunch of money so I just tried with a basic dslr/lens. I bought an intervalometer with the intention of using deep sky stacker to stack multiple captured meteors in a single image. a very optimistic plan I suppose in hindsight. shoot was only 2 hours or so in two parts due to cloud cover. I learned that the sky is littered with satellites that can ruin a series of shots, and that for great clarity either a motorized tracking camera mount or a great lens needs to be used with a shorter shutter time to minimize smearing of the stars. probably you need both and a moderate shutter speed. I learned that I should not use the little built in lcd to determine shutter speed. also realized I know fuck all about editing. I had some "photography" friends who said it was hard, I should have listened. basically, I found out the hard way how inadequate my equipment was, I would need a significantly more light sensitive lens/aperture. Even in a bortle 2 area, the milky way didn't photograph well, perhaps it was a bad night for it. andromeda showed up better than the milky way, weirdly. it was still a beautiful night. saw a proper fireball as I was setting up, heartbreaker. here's a heavily jpeg'd raw of a meteor I captured...theres also a satellite.

>>4341374
my trust ol' canon t3i, this is the stock lens 18-55mm f/3.5-5.6. I shot all the way up at ISO 6400, but I think there's too much noise. maybe I could have lowered the ISO, but I was already pushing it with the shutter time, and would have liked a bit shorter exposure. It turned out that I was a bit in a rush to get shooting. c'est la vie. i was trying to find the jpg output from the camera since it gets rid of a lot of the noise, but couldn't find it. that might tell you something about how often I edit photos.

Another regular dude here.
Exif in the pic, bottom-left. Original size 6000x4000.
Yeah, your ISO is way too high, but depending on what you want to capture sometimes you just gotta. My camera was riding on top of a telescope with a clock drive, so no streaking. Swapping ISO for time (6 minutes here) is a huge bonus. When stars are sharp, the light concentrates and you get more stars. However, I discovered that this camera's sensor heats up on long exposures, and the brightening/reddening at lower-left is what it does.
An option to mitigate the noise is to take another shot of exact same duration but with the lens cap on. Then you subtract that frame (which has nothing BUT noise) from your photo.

It doesn't look so bad after converting it properly from RAW, but ISO would probably still be better lower. I think the sensor overheating is a common problem for this kind of photography.

Thanks! I'm going to try again this year, and hopefully get more shots like this that I can stack together. I'll try that lens cap trick as well. I also wanted to try to make a barn door tracker, though I don't know how well that would work for stacking, since the apparent radiant of the meteor would change. That would have to have no foreground if I tried that, which is fine because I don't know if I like it as much as I thought I would.

Very possible, just simply inputting them into deep sky stacker didn't seem to work everything was misaligned, I thought this was because of the movement of the sky (perhaps because of parallax)? I only really had the one good shot of a meteor due to short shooting time (clouds)

Your subject is not unique, but your foreground can be. That's where a lot of interesting astro begins. Think of getting some landscape into your foreground in creative ways.

Refractor telescopes can be used as "lenses" (but not reflector) for DSLR/Mirrorless cameras to get incredibly "zoomed" shots without spending $20,000 on a canon L lens. All you need is a T-adapter which for me was like $30.

Wider lenses allow longer exposures which allow more light / better quality shots. Once you hit a certain point, your stars will have tails which make it look less sharp / clean. To avoid, follow the 400 rule (google it). Wider lenses also get more space into your shot which looks good.

You can also embrace the tails you get with long exposures to great effect, by intentionally setting very long exposure times 30m, 1h, even all the way through the night 8h+. This produces shots with a "shape" to them as the Earth rotates on an axis and draws part of a circle in the sky with the stars. Can look amazing but since you need to do very long exposures there's very little room for error in this style. You can spend an entire night / morning on a single shot only to realise the settings weren't dialed in properly or you bumped it in hour 3.

Light pollution is your biggest enemy. If you live in a city, rip. Not to say you can't get decent shots in a built-up area, you're just fighting against it. I live in an area with terrible light pollution, but if I drive 30 minutes away there's practically none. The amount of interesting things you can actually see in the sky is dramatically better in comparion to sitting in a city.

Tripods are your friend. You need one full stop. Pair this with a remote shutter and you're golden. You can also buy very expensive astro tripods that have gimbals and rotate with the earth to completely avoid the stars producing tails. This is endgame kit for getting the cleanest, brightest shots.

Best fun I've had with photography. Good luck.

Fuck me, I'm actually misremembering... there's a certain kind of telescope that won't work with it. I swear it was just the cheapest type and I could have sworn that was reflector. I was wrong on that part.

Ah - you must be thinking Dobsonian. This refers to the mount, not the scope itself - the least expensive and easiest to make at home. All Dobs are reflectors because a refractor would be limited to low-altitude objects on a classic Dob mount. Anyway... it's an Alt-Az mount, which means the field of view will rotate in long exposures. They can still be used for shorter exposures, as with solar system objects or bright nebulae. There are two ways to mitigate rotation:
1) Field de-rotator. It's like a star diagonal with a motor what rotates internal mirrors to counter-rotate the effect of Earth's rotation. It's an expensive device (minimum $800).
2) Equatorial hybrid Dob mount. This is basically a Dob mount tilted at the same angle as your latitude. You need to polar align it, and it's hard to do.

Ah, cheerio mate. My telescope knowledge ends pretty quickly. But yeah, that sounds about right. I had a friend that worked at an observatory for a few years and she went far, far down that rabbit hole. She had what I'm guessing was a de-rotator and some fuckoff expensive, super long range telescope she would set up and show me stuff with. Didn't have the kit to take photos with it at the time which is a shame because what she could find was astounding.

I'm currently limited to an Alt-Az w/ 800mm reflector which is basically fuck all, but is still useful to get better reach towards specific objects / nebulae. Not sure if I'm prepared to start emptying my wallet for a long range kit but is certainly something I will get around to.

That's an impressive 18 inches anon.

It is. The guy did a superb job of building the mount. He bought the mirrors already configured. I shot the image at a star party in 2004.
Mine's the black one at right, pointing horizontally. I wanted equatorial.

I never really noticed before, but I think the guy front and center with the white scope did the equatorial adaptation. That big silvery disk looks tilted parallel to the equator and I see a pivot bottom-right. Look how my forks are pointed - that's celestial north for the latitude.That's where his axis is pointing, too.
Here's the only other shot I have of it, part of a panorama. The old dudes are checking it out.

Thanks for the advice, senpai. I'll be screen capping this and saving it in my reference folder.

I have a few more questions if you don't mind.
1. How many months/years into amateur basic astrophotography should I do before "jumping the gun" and spending thousands on a larger higher-grade scopes.
2. If you can give a ratio on how much I should allocate my budge for the most "bang for my buck" between telescopes and cameras, what would it be?
>>
>>4343036
NtA, but...
>1. How many months/years
When you feel you're ready and can afford it without hardship.
>2. a ratio on ... telescopes and cameras
I'd lean more heavily on the camera. It's more versatile and likely to get used more often. But maybe you're more interested in visual.
It's up to you to know.

Deep space gets fucky without ideal conditions. There was a more advanced astro nerd in another thread the other day that would know more, but I've tried doing similar stuff and failed many times. Still yet to get anything remotely good since I cant be fucked being up at 5am; I had photos of Venus that came out looking like a yellow smear thanks to the sheer heat coming off Earth 11pm. So much of astro is just planing and conviction.

this is the last one i'll post, there's a bunch of other meteor shots in similar series, but the aurora kind of stole the show.

I still plan on buying a lens with a bigger aperture so I can shoot at lower ISO's. looking at rokinon 14mm f/2.8

If you're saying that the name of the white balance doesnt mean much, at least for astro I've found that to be true. I don't know anything I haven't learned through experimentation though

how far into sharp DSO photos can i reasonably get with this setup? i'm about to buy a house soon so i'm looking at one last big purchase before i turn into hank hill. so far i have everything except and EQ mount and astronomik UHC light pollution filter. astrobin suggests that it's less of a "spend $10k" issue and more of a skill issue

- canon EOD 2000D that i astro modified with an astronomik clear glass filter
- 75-300mm f/4-5.6 kit lens with 58mm aperture
- slik pro 700DX tripod
- Sky-Watcher Star Adventurer GTi Mount Head
- also considering Celestron Advanced VX Equatorial Mount
- astronomik UHC clip-filter (picrel is the transmission curve)

i'm also open to buying a used Canon EF 200mm f/2.8 L USM lens but that'd probably limit me to the star adventurer GTi. both mounts are goto and data processing isn't a problem, i have a beefy virtual machine set up for this specific purpose. i'm already skilled at microscope photography, just trying to avoid a situation where i limit myself to only andromeda or something
>>
>>4351426
Should be capable of some good images. I run an Eos77d with an ancient 200mm lens on a Lightrack ii. I get images similar to those of M31 Andromeda and M42 posted earlier (cropped somewhat) after mucking around in Pixinsight.

I occasionally pop an Astronomic UHC-E clip filter in and results from that are mixed. Blue and green channels are much better but I end up with unpleasant red halos around stars which are difficult to process out. I think this is something to do with the thickness of the filter as Astronomik have just released a range of filters using thinner glass.
>>
>>4351502
thanks. i kinda suspected this based on nebula photos, sarah maths, and that channel with the french guy and his short, kinda fat wife (galaxy hunter?) but it helps to have some independent confirmation, and ppl ITT have recommended some great advice before in past months like the AVX. incidentally, there's a teenage girl on astrobin using mediocre gear with no mount at all, producing some rather impressive photos

obviously i still have no EQ mount cuz i'm not gonna drop $1k on a whim, but in the proposed setup, there are probably about 30-50 objects i can reliably get really good photos from. this is going on the youtubers' circlejerk about the 135mm f/2 rokinon with a basic star adventurer 2i tracker. but it's easier to upgrade the rokinon/2i with better gear at the same price point today, which for me is about a $1k limit give or take a few hundred $

it seems like the best option right now might be the EF 200mm f/2.8 L USM lens + star adventurer GTi mount for its sheer versatility. i'm much more interested in having one core photography kit for all domains (astro, micro, normal) centered around a cheap crop sensor and the best quality optics and accessories that vary in quality depending on their importance, with a solid goto mount being more important than a $20 chinkshit intervalometer. same reason i paid extra for a basic nikon labophot 2 but it was fully outfitted with PLAN objectives

portability is also a huge concern, as the closest uncontaminated site to me is either deep in western mass or near the white mountains in NH. while there are some less contaminated spots looking out over nantucket, etc., i'm most likely to image on a camping trip in NH. incidentally, my eclipse trip to st albans, VT was based entirely around camping and we never stayed in an overpriced airbnb. but sadly i didn't think to compare the kit lens vs some random shitty old 400mm lens off ebay so my data is garbage :/
>>
>>4351510
i'm kinda rambling now but it seems entirely possible to get a capable cross-domain specialized photo setup, built up over years, for like $3-4k max, the difference being skill and experience. even just looking at my oldest vs. newest microscope photos on the exact same equipment, the difference is huge. and i haven't even started using siril calibration in microscope photos yet, being too busy with this house business to image pizza ingredients (my current project is to image cheese, salami, sourdough starter, onion, mushroom, tomato, etc.)
>>
>>4351510
My lens was a drunken ebay gamble a while back but has worked out really well (not many around so won't id it and thus myself). It's quite a fast lens but had to 3d print some aperture rings as stars are slightly blobby wide open and I get nasty (almost iron cross) spikes when I rely on the iris... I would like to get hold of a 300mm lens but have teenage kids and an ailing missus to feed, so that can wait.
I couldn't justify a proper mount but did stretch a bit for the lightrack (and later on the counterweight kit). Star hopping to find a target is a PITA but once setup tracks beautifully, if only for 2 hours is before I have to rewind.
I will get a better tripod. Mine wobbles a bit when I try to align the drive.
I'm in southern England and skies aren't great, but I get the odd good night without cloud cover (last year was shit). Sometime I will have to get a proper astrocam and some filters. They're developing in our area and the skies are getting brighter.
>>
>>4351531
lol my lens came from ebay from the UK, total strike-out. the quality is so soft and there are imperfections that have to calibrate out. i wish i just used the kit lens cuz i sourced a good jap-made one

sadly the difference between an 200mm and 300mm L series canon is like $1k+ so it's not worth it for me. i'm in southern new england where it's a cloudy, humid hellscape basically the whole year so i can realistically get like 6 good imaging sessions per year, that may occur on random weekdays in the middle of mud season

the closest 1-hr drive areas to me are in some beach and in north scituate RI, though i can probably get bortle 3 closer or the dark area of south yarmouth on cape if lucky

don't live in civilization, bros
>>
trying to finalize the shopping list. it's easy to see where the gearfag stereotype comes in, with reddit saying "bro just spend $500 more on an HEQ5," when that $500 is the difference for me between f/2.8 and f/5.6

looking into the AVX, it really seems hit or miss as far as quality control goes, and weighs a massive 47 lbs vs 16.2 lbs for the GTi. i'm also not impressed with people's opinions of the EQM-35 and am aware that sky-watcher tends to use shitty grease and bearings, which i can fix

high point has a pretty banged up EQM-35 for cheap but as far as i understand, you can't use it with a dSLR without removing the declination assembly, making it basically an overpriced 2i? also, buying a telescope seems pointless with a $350 used EF 200mm f/2.8 L-series easily beats a $900 redcat 51

so this seems like the best balance of capability and weight on a loose $1k budget:
- Sky-Watcher Star Adventurer GTi Mount Kit ($740)
- Astronomik UHC Clip-Filter EOS APS-C (€116.81)
- used EF 200mm f/2.8 L USM ($350)
- bhatinov mask ($10-20)
- used ipad ($150)

sadly, my existing tripod only has a 5 kg payload capacity. the ipad would be a nice interface to SynScan, stellarium, and astrospheric, as well as being an LED panel for clean flats. i already have a dew heater, camera body, and intervalometer. this setup should unlock at least the messier catalogue, i imagine
>>
>>4351811
oh yeah, i'd also need a vixen dovetail plate with a 3/8" screw sticking out of it to actually mount the telephoto lens ($20-30 on amazon), and maybe a couple of cables and a good power supply for the mount. i already have a USB battery adapter for the camera and a good anker 20k mAh power bank that can power both the camera and dew heater for hours
>>
>>4328138
these extremely autistic articles helped me see the benefits of using a crop sensor with the widest aperture lens as being a good value solution, considering the inherent risk of ruining a $1k+ full-frame camera vs a $250 crop sensor to modify it. and the pre-modded (really just lacking the normie filter) EOS Ra, if you can even find it, is like $3k. but there's no free lunch, as the higher pixel density increases noise because each pixel's signal : noise ratio is worse

this can mostly be calibrated out, obviously, but the net result is more noise and a lower limit on aperture diameter. that being said, i appreciate the crop sensor's higher effective focal length vs the full frame, again at the expense of more noise distributed through the frame vs concentrated at the edges, which would be cropped out anyway

that's my train of thought, and i'd probably be looking to upgrade my camera body to full-frame at some point within 5 years. i just checked on ebay and 30 MP full-frame bodies are going for $500-1k, which was not the case when i bought my camera. at that time they were like $2.5k or so
>>
>>4328138
because normally photography works in terms of scene exposure, not light gathering.

the wider angle, smaller aperture lens has the same fstop because its gathering a wider field of light and therefore the same intensity, but it's not more light from the subject unless it gets close enough (inverse square law says get closer for more light). launch your 15mm f2.8 into space, easy!

45 MP canon EOS R5 going for $500 if anyone's in the market right now. it's not the most amazing camera in the world, but received wisdom is that if you're gonna spend big bucks, spend it on the optics and mount, not the camera itself. i wouldn't be surprised if these were going for half the price in a few years, putting it on par with my $250 used EOS 2000D

dunno, there's this weird space in ebay between total randos and mega stores that's elusive but comfy, usually populated by individual people who sell off personal possessions cheap, or running small side business. still speaks to my point that used camera bodies are coming down in price and that you don't need the best camera if you're gonna sacrifice on glass

i've been studying this guy's setup from cloudy nights, trying to get a feel for how everything would fit together before actually spending any money. originally i was just gonna do 3-star alignments on a GTi via SynScan and use a manual intervalometer, but people say the SynScan app sucks ass and that 5' exposures are pretty much the GTi's limit with perfect alignment and balancing

it seems like adding a guidescope/camera as pictured and running everything off astroberry is an affordable way to push the limits of the GTi while still maintaining a high degree of portability. i could also wirelessly control everything via a cheap used ipad that doubles as an LED panel for flat frames, which based on my solar experience, are the most important calibration frames and the hardest to get right

so for this i'd be looking at maybe:
- iOptron iGuider package ($233)
- or a similarly priced ZWO option
- RPi 5 ($80 max), GPS hat ($30), and maybe a case ($20)
- cheaper than an asiair mini ($200) at the expense of power output
- could downgrade to an RPi 4 and use my 9V/3A anker battery

also, clicking "random page" on the astroberry wiki leads to some very odd spam. i was originally hoping they'd have a guide about controlling an EQ mount and dSLR:

>>4352152
also, this guy is using the same exact tripod i already have (slik 700DX pro) with the star adventurer GTi:
https://www.youtube.com/watch?v=mlutuMZkVWo

it's rated at a 5kg payload capacity, but i dunno if that's with the legs fully extended. it's a pretty good tripod, so maybe i can save $100 by buying just the GTi head and keeping it low? i already expect to use a bear can as a stool anyway
>>
>>4349011
>tips on focusing in the dark would be appreciated
Looks like you've got that pretty well dialed in. I pick the brightest object up (in your shot, Jupiter), center it, use live view, set the lens zoom to the field I want, digitally zoom in to manually focus, then back to frame the sky.
In you particular shot, it apparent the camera shifted position slightly during exposure as there are doubles of almost everything.
Your lens looks great - almost no coma except for a hint of it at top-right. I have no lens so good.

i posted this before, but one of neighbors got a shot of shoemaker-levy 9 about to crash into jupiter in the mid '90s. pretty interesting piece of astronomic history cuz nobody has ever observed a crash like this in the history of the species. also, the fact that he got such high planetary resolution on earth with '90s tech is technically impressive. the lighting artifacts are from my lamp/daylight, not inherent to the image itself. this is one of my favorite photos of all time

honestly, the fact that you're getting such good resolution of such relatively fast moving objects like planets is a big feat. it's pretty wild that your 1st attempt can exceed a professional amateur astronomer with 5 years' experience a mere 2 decades in the future. keep at it and you'll do great things for sure

the tripod in this configuration should be more than stable enough for GTi mount, no? it actually seems better than the sky-watcher tripod that comes with the mount. the legs are about 32" apart. are there any clearance issues i have to worry about with it being so low to the ground? the older version of this lens is only 5.4" max length:
https://www.usa.canon.com/shop/p/ef-200mm-f-2-8l-ii-usm

so the optical train would be, from front to back:
- 200mm f/2.8 L-series
- atronomik UHC clip-filter
- canon 2000D full-spectrum mod
- iOptron guide scope/camera bundle

cabling and connectivity is still confusing but it may look like:
- 2.5mm jack from main camera to mount SNAP port
- USB to telephone jack (?) from guide camera to mount AUTO GDR port
- USB type B to USB-3 type A from mount to astroberry
- use the RPi's 2x USB-2 ports for 2 dew heaters
- power the RPi off a power bank via USB-C
- power the mount off AA batteries
- power the camera dummy battery via power bank
- control it with an ipad connected to astroberry AP
- i may need a 2nd power bank or preferably a real portable station

does this make sense as a comprehensive look at a budget beginner setup that punches above it's price/weight class? i have an email in with high point trying to make sense of it all before i buy random shit that doesn't work together

On a scale of exposing a picture, planets move very little differently than the whole sky. If you're using a clock drive for taking images, planets will appear stationary for orders of magnitude longer than require exposure time.
Your concept of planets moving any faster than the rest of the sky for imaging is simply retarded. In fact, while in prograde motion, planets have a slower angular velocity than the rest of the sky.

high point got back to me and basically said i was right on the money, except i underestimated my power needs. so i'd prolly need a $100 anker device with enough wattage and amperage to do the job, prolly using my existing power bank to fill the gap and maybe even a portable solar panel i have but never actually used

so it seems like a reasonably good widefield 200mm DSO astro setup with extra features like software controlled autoguiding and GoTo functionality, can be had for $1.5-1.8k, in a form factor light enough to pack into a duffel bag and carry into the mountains

the autoguiding itself is a luxury mostly to push the setup to its limits and take full advantage of a mini computer like an astroberry. if i could get say 10-12 hrs of light frames with 5' exposures and a 25% reject rate, that's a lot of good data for a weekend camping under dark skies

that's not a terrible price considering my used microscope, camera adapter, various filters, and consumables like slides, glycerin, and kimtech mounts cost maybe $750 total. and over $500 of my astro budget is unnecessary luxuries but definitely nice to have
>>
>>4352790
well, after going through every aspect with high point, i'm ready to click a button a watch a large amount of money leave my bank account when i'm sober, and after about a year of virtual gearfagging i can soon take some heckin photorinos. i have a reasonably accurate idea of this system's limits and especially its cost effectiveness, and am confident that it won't be obsolete even if i had a massive planewave telescope in a private observatory, since being able to pack up and go off grid to katahdin is better. i also have a clear idea of what transfers over to some hypothetical permanent setup and what's necessary vs. a luxury. for what it's worth, high point didn't try to aggressively sell me stuff, which is a refreshing change from youtubers saying "you can totally do astro on a $2k budget, BUT here's this $10k gadget someone lent us for free and it's better than indoor plumbing and the smallpox vaccine combined, so you need to buy it right now"

To be honest with you both, I genuinely believe planetary photography is much easier than deep space. My set up is jank and the precision required is so much less than that of what you need to get some of the nice images from earlier in the thread.

I have a cheap camera mounted and wired to my laptop using default software, and just manually keep the planet in view with an alt as mount, not using any guiding software. Yes, the planet does move relatively fast across the sky but as long as I keep it in frame it work out. I then just take the video I recorded for 1-2 minutes and stack the good frames of it together.

I appreciate the positive feedback though. I tried to get some more images earlier this week but again the humidity is ruining the quality.

Was messing around on my new Pixel 9 Pro early this morning and I've fallen in love with Astrophotography, but as a student poorfag I can't really drop anything more than a grand on a beginner setup. I'd like to start taking closer shots of galaxies and gas giants, but I'm unsure if this would be out of reach on such a reprehensible budget. I also know basically nothing about photography as well, I'm entirely dependent on AIslop for good photos. I'm going to start learning on my own, but if any anon can point me in the direction of proper guides/education I would be insanely grateful.

MFers I signed up for an Astronomy minor, started with a 101 class by a hot shit new prof that started with calculating the density, type, age, mass, and energy/mass loss of distant stars, and did another 6 semesters of that shit. Never once did I get anything like the interesting tour of the galaxy I was hoping for, and I have no fucking idea looking at the sky where anything is or what I'm looking at and I was never interested in reading another thing on the subject again. I know Andromeda is close but only from watching the Andromeda Strain as a kid. I have no fucking idea what any of you are talking about and it makes me very sad, bc I loved the idea of this stuff as a kid.

Get thee to ebay.
Search for H.A. Rey's "The Stars: A New Way to See Them" (author of the Curious George series) - get a used one for about $4.

He makes it really easy to learn the sky.
It helps if you're in a light-polluted area to have small, wide-field binoculars.

>>4359370
>Does this look like light pollution?
Not really, but I can't offer any other ideas. It's very strange to have a spot high up lit up like that. It's either a large portion of the sky from someplace along the horizon (liek toeards a city from outside), or it's all over (you're within the city's light dome).
Another guess is your camera has vignetting issues.

maybe on used equipment you can get the stuff you need: the cloudynights classifieds, astromart, or astro buy sell or all decent places to get used stuff. Ebay can work as well, and sometimes you can get lucky on facebook marketplace.

Generally though, if you're getting all new gear a basic set up for anything dep sky gets close to 2 grand. You can take about $5-600 off that total if you already have a decent DSLR camera, which it looks like you might.

At this point you need a mount, scope, and something to run it all.
The mount is the hardest part. They rarely go up used and are expensive. You'll want one that supports about 11 lbs. You can usually get a decent one for about $3-400, but you'll need to get a tripod to go with (but that's easier and cheaper). Some come with one.
The scope is easier, you can find a decent one used most of time as people are always upgrading and trying to sell off their old ones. A small refractor works well, get one made for photography. I got a Williams Optics redcat and that shit is amazing. Realistically, you should be able to get a serviceable scope for about $500.
You can use a phone, tablet, or laptop generally to run most of these things, just be ready to have some jank and work through some tech pains. If you already have a laptop you're for sure set on that.

Lastly comes the bullshit little things I forgot about the first time I tried to do it all. Something to attach the camera to the scope. A power source if you're driving out (a cheap camping battery works). The rest you can improvise or work around.

My brother-in-law introduced me to this scope he was interested in buying. It's an imager - you don't look through it, so I'm not interested at all. But if you're into getting images, it's an economical ($600) solution, but I haven't seen it in action. They have several facebook groups with spectacular images. I have have a hard time believing it, but they seem to be end users so... maybe.

yes, i'd say just buy the cheapest used DSLR possible, the best L-series lens he can afford (200 mm 1st gen L-series prime is $350 used on ebay), and budget for a GoTo star tracker as a nice middle ground between a cheap-ass 2i or a $2k+ EQ mount that holds a gorillion lbs. asiair mini is $200 extra, autoguiding is another $200 or so, factor in another $100-200 for misc accessories like vixen dovetails n dew heaters n shiet, and unless he's tethered to mains he def wants a battery that delivers 12V/5A DC output (another $300), shit adds up fast

i'd also strongly recommend against using cloudy nights for anything but the classifieds, you don't want to ask them for advice, because it's a boomer consoomer forum not a citizen science one and the answer is always gonna be, "the hobby's so expensive so just spend an extra $500." also, do NOT in any way ever suggest that spending less than $5,000 is a good idea, you've been warned
>>
>>4359815
i'd go so far as to say that if you're not using cloudy nights exclusively to sell products and services, you're using the site wrong. it's kinda like reddit in that it's a content marketing platform not a real forum, except you have a captive niche audience who thinks nothing of spending the average wagie's monthly paycheck on some meme like a chinkshit strain wave mount. in fact, my singular goal for that site is to shill a patreon where i'll publish guides on advanced data processing topics

I assume the Pixel phone series also uses image stacking but does anyone know how many images in the astrtophotography mode are stacked in the 4 mins while it is shooting?

I just recently bought a dslr so most of my shots of stars were shot with my old pixel 6 pro but now that i have a proper camera, i want to recreate those shots but better.

Just bought a DSLR tripod that also has a phone holder attachment, it arrived today. I'm having plenty of fun with my Pixel still. Planning to get a DSLR next, and then learn the device as well as practicing some better photography technique. In time I'll have everything you mentioned I believe. Thanks again for the advice

>How do you become so adept at spotting constellations btw,
I search around for a familiar pattern somewhere. In that picture, it was the head of Draco at the bottom that caught my eye. Then I worked my way from there and frankly had to use software to help me along. I use an old Windoze 3.1 version of Chris Mariott's "SkyMap" because it's portable - no install needed. It's MUCH easier out under the real stars. For one thing, I know where I am, what direction I'm facing, what time of year, what time of night, you don't see nearly as many confusing stars as a photo shows, and the differences in brightness are more obvious.

Looks like there's a comet that's been visible for a while in the southern hemisphere that will be visible in the northern hemisphere starting from this Sunday, and it's supposedly the best day to see it. Though thorough the week it'll still be good. Supposedly it's very bright and has a nice tail, a once-in-a-few-decade comet. Pic of it.
Unfortunately I live a few kilometers away south of Paris, I guess I'm fucked but then again those are very bright objects, I might try my luck. Surely the camera sensor will manage something. I won't be able to go far away from the city and all the other cities in the surroundings, unfortunately.

I've been waiting for it to show up, but it's been cloudy non-stop here in Jura. I wonder what size this thing has, best I've got is a rather dark 300 mm lens.
My understanding though is that the comet is starting to be visible and will be easier and easier to see until oct 25th, one need to look for it right after sunset.

By my reckoning, the comet will reach greatest eastern elongation on the 22nd, +/- a day.
The Moon will be Full on the 17th, and waning gibbous on the 22nd - wholly out of the way.

I thin I can help with this. I'm drunk so take everything I say with a grain of salt. The best thing you're going to need is a telescope that is a light bucket and a purpose built camera. If you live in a city oyu are fucked. You will need to drive out to hte country to avoid light pollution. I would recommend a dobsonian scope at least 8 inches in diameter but if you have a big car and lots of strength maybe a 10 or 12 inch. the wider the mirror the better. You need to gather as much light as possible not zoom in. Zooming in telescopes are for gay virgin planet shooters and everyone knows that planets are the gayest thing to photograph. Can you imagine? You can already see them with your eyes what do you need to photograph them for?

Anyway, get a big dob, and then get a purpose built astrophotography camera. I recommend chinese shit because they are fine and the same as expensive pro gear. I like the company SVBony. If you want to be autistic about it you will need a mono-color camera and a color wheel to shoot in color. If you are lazy you can get a color CMOS and enjoy your lower resolution. I just got a color CMOS and dealt with it. Then you take your exposure- preferably a lot of them, and then use a program like Autostakkert to stack the photos into a high-detail composite.

Enjoy taking your photos. PROTIP: If you are truly interested in predicting events by the stars I recommend you read "Helenistic Astrology" by Brenan to start yourself out on the divination of Astrology, and then learn how to read star charts you look up with an astrology augur. If you are looking for an augur program I recommend ASTROLOG32 from the Altervista website but this has nothing to do with photography and more to do with /lit/ garbage.

With this knowlege you'll be shooting the stars in no-time, and by that I mean you'll be letting your camera collect dust because actually viewing through a 23mm Plössl glass is more fun than spending thousands on a photo setup.

That 50mm is good enough wide open for nighttime landscape photography. What is it?
>>
>>4374001
fuck that shit, if he wants to photograph comets then a dslr camera, a 100-400mm lens and a startracker like a star adventurer gti is all he needs. If he wants to shoot nebulae and galaxies and shit then an alt/az dob is gonna suck ass due to the alt/az guiding. For long exposures you need equatorial mounts.

Specifically for comet A3 which is visible now you literally only need a smartphone. A DSLR with a stock 18-55mm lens makes even greater photos of the comet and the long tail. It is my no means an object which requires specialized equipment. However, not all comets are equally bright and close, and the vast majority can not be captured by just a small 18-55mm lens. Most of the time you need atleast a couple hundred mm of focal lenght and long exposures >30s to capture them.

>if he wants to photograph comets then a dslr camera, a 100-400mm lens and a startracker like a star adventurer gti is all he needs
The cost of a DSLR vs a dedicated astro-camera for what you are going to be able to do with it, the astro-camera is a better value, especially considering taking long-exposure and multi-capture/video for stacking, astro-cameras have built in fans for cooling (the more expensive ones) and give you a higher level of detail because Mono-color CMOS censors will capture more light at a higher resolution than color CMOS- You're losing detail because you're trying to capture colors you don't need. You'll get better results with a color-filter wheel on a B&W sensor. The only benefit of a DSLR is you can use it for other things and someone might have one already. Sure, comets and other larger phenomena can be shot with a DSLR but only if you already have one so it's not spending to buy a camera like that JUST for photographing stars. A garbage reflector with a cheap chinese B&W astro-cam will take better pictures at a better cost than whatever DSLR you have.
>shit then an alt/az dob is gonna suck ass due to the alt/az guiding
Now that I'm not drunk I agree with you, Meant to say Newtonian mounted on equatorial I mistakenly call all cheap reflectors "Dobs" when that's a specific kind on a specific mount.

>The cost of a DSLR vs a dedicated astro-camera for what you are going to be able to do with it, the astro-camera is a better value

Absolutely true. However it is far more likely that people have DSLR cameras laying around as opposed to astro cams, not knowing they can use them for astrophotography. Obviously if you want to go hard on the hobby, by all means dedicated astro cam all the way. Shit now im questioning if i should go one shot color or mono w/filterwheel. The filters are just so god damn expensive...
>>
>>4374657
There's two problems with this way of thinking. The first is that while people are far more likely to already have a DSLR, the DSLR they have is going to take absolutely dogshit astrophotos for the most part. Assuming they have a wide enough lens to get anything good, they could spend the money on a telescope. Also, if you have a smaller scope (sub-6in) and are using a standard 1 1/4" Eyepiece there's a really good chance that the focusing assembly will push the camera back too far, so far you won't actually be able to get a picture in a DSLR. This is not a problem with an Astro-cam because it is purpose built. 2" Eyepiece focuses and 1 1/4" with helical focusers don't seem to have as much of a problem, but most people don't have that big of a scope lying around.

I have to say, I'm rather disappointed that no-one ever commented on my comet photo.
>>4327204
For the record, it was taken through a 3,910mm f/11 Schmidt-Cassegrain at prime focus using a t-adapter and T-ring, using a Nikon D5200 exposed for 20 seconds at ISO1600 under a Bortle 8 sky. It's resized to half dimensions (quarter area), and slightly edited gamma, hence the loss of exif.
I happen to think this is a fairly good shot for a relatively inexpensive prosumer-level DSLR camera that I can use for a wide variety of photography, though I acknowledge astro cameras (we used to call them "CCDs") yield far superior results. But at that point I'd rather let gearheads spend time and money making the good shots of stuff I'll never see with my eyes - it'll only ever show up on screens anyway.
Here's another - M13. Same sky, again resized, 15-second ISO 1600 exposure. Nice thing is, when you look through the scope, this IS what it looks like.

What is that, a 14" scope? That's got to be fuckin' huge. You must be taking this shit pretty seriously to have such a klt.
I don't get the hype between the whole "you can't really see this" stuff. I'd much rather just see it as reality intended. I can use AI and heavy photoshoping to get unrealistic views.
This kind of medium/deep space shit is fantastic. I don't need it to be crystal clear, or absurdly detailed; this is shit that is unfathomably far away from us and we get to look at and take photos of it as if it was just upstairs from our kitchen. Berry gud.

One day I'll benny up for an equitorial mount and an 10 incher (at least). I get the feeling a lot of astro is planning out what nights will have good visibility and predicting what objects will be visible, then finding and tracking them. Kind of like a hunt in a way. Until then I'll settle for regular astro photos, especially since hauling a big scope will be a problem with a motorbike.

I started with a shitty DSLR and shitty 18-55mm lens and i took my first untracked pictures of both the Orion nebula and Andromeda which then led me to investing in real astro gear. While the pictures are of course, pretty shitty compared to tracked long exposures, its still an excellent gateway into the hobby.
And many people believe that you need a scope or some kind og tracking or a special camera to catch these objects in the sky, but you dont.

If I had one scope, I agree it would be the C11. But I had a C8 and found the C14 with eyepieces and a bunch of accessories for a very good deal and couldn't pass it up. But yeah - if I had the C11 it would have been everything I wanted.
A friend has the C9.25. I have to say, the optics in that blew me away. If it came down to it, I probably would have been happy with only that, too.

Your picture's focused, buddy. Two things:
1 - Looks like your mount was shaken during the exposure (windy? But then the grass and/or trees would be out of blurry - they kinda are). I don't think the mount failed or sagged (weak mount, or its lock levers don't hold - overloaded?) but that's a long explanation leading to a stronger guess it was moved near the end of exposure exposure.
2 - At 25 seconds, you're picking up star trails (shows proper westward motion streaks - this isn't from a sagging tripod), even with a 28mm lens. Only ways to fix that: barn door pseudo drive, proper equatorial mount, or field de-rotator.

For focusing, those tower lights are plenty far away, and if they're not bright enough to see, perhaps a new brightness setting for the screen would help (pic related)?
>>
>>4375440
In my experience the best is still focusing in liveview at maximum magnification, aiming towards a bright star (and deactivating autofocus ofc).

I bought my C11 back from the dude I sold it to. Feels good, man. He hadn't even used it yet.
I'll build a permanent pier for the C14 next year or something. I much prefer driving to clear skies rather than waiting, hence me being apprehensive about the 14 especially in the winter. I'm setting up by myself 90% of the time and the C11 is nice and light and easy to manage alone in the dark.

So I went outside to try to catch some meteors Sunday morning. I brought my Svbony 10-30x 50mm spotting scope with me for kicks and I ended up spending a huge amount of time looking through it. Getting images in focus was a challenge but I was able to barely make out Saturn's rings (looked like a line) and saw Jupitor's moons with it. Because I enjoyed it so much, I'm going to pick up a used telescope. I found a Celestron Astromaster 70AZ for $60 CAD (70mm aperture x 900mm focal length and F13 or something) that will hopefully be in my hands Wednesday.

And of course, I want to try astrophotography with it. Besides a T2 to m-mount adapter for my Sony APSC camera, do I need anything else? Do I need a Barlow lens? If so, is there a way to tell what magnification barlow lens I'll need before the T2 adapter arrives? I'm hoping to order everything together. Celestron doesn't say how big the image circle is.

You can, but you won't get the best exposures at f/13. It will be even worse with a barlow.

As in you'll want to take multi-second exposures and at 900mm everything will move quite a bit, resulting in streaks. You will have to stick to very short exposures. It will be great for something bright like the moon though.

It'll be great for the moon, definitely don't worry about that. You'll still be able to get planets too, it just won't be ideal since you'll need a pretty high ISO. I've used the 70AZ before, it's pretty good all things considering. Get some better eyepieces though, they are its weak point as a package.

I'm saying unless you discover a predictable, testable, and verifiable cause and effect, your statement claiming to have found truth to a relationship could be explained quite easily as unrelated coincidence.
Similarly, dying by bed sheet entanglement and consumption of cheese have no cause and effect, though their occurrences have superficially coincidental trends.

Nice! It's a solid scope for the money, especially for visual use. Imaging isn't everything, I just observe 99% of the time. It's also lightweight meaning you can get a very cheap mount if you ever do decide to get into guidance.
>>
>>4376967
>Video follows the exact same rules, bucko
No, it doesn't.
Cameras that also do video typically record in much smaller resolution than a dedicated still shot would. So it would be good to get a full-resolution image instead. A huge advantage to video is that the shutter doesn't open and close between frames. Tripods and mounts are classically under engineered, and the shutter going off is enough to cause vibrations that ruin the shot. The solution? Take long exposures for stills. Any shutter shake should dampen quickly enough that the motion blur would be very dark, leaving a good exposure of the object as it's stationary. The problem with that is, you need better and better tracking for longer exposures and focal lengths, and planets are so bright that it's difficult to take exposures long enough.

Nothing impressive, but I'm still happy considering it's under a heavy light-polluted Parisian sky. A7c + Sigma 90mm f2.8, stacked 15x4sec photos, first time I tried using stacking.

I did the shot yesterday, it was cloudy all week unfortunately, and we already lost 1 magnitude on the comet since then. I heavily darkened the photo in post, truth be told, but surprisingly not too much at the expense of the stars and the comet. I had to deal with the street lighting, cars passing by, and the Eiffel Tower doing her attention-whore and lighting up the sky like a lighthouse.
Surprisingly, I didn't have to fight orange as much as I thought I would have to. Pic related, spot where I took the comet from (old castle grounds of Meudon, 2km south of Paris).

It's the traditional way with older cameras. All issues (including heat) are solved with a dedicated astro cam of course, but most people just use what they have.

Surprising indeed, especially with a bit of clouds which tend to worsen the light pollution. But then again it was probably even cloudier on my shot.
I'm kinda surprised that you can still see the comet that clearly, as you said it's faded a lot.

imagine you live in the southern united states bordering mexico
or on a coastline
you get to see on your TV and outside your window all the illegals coming over the border
you SEE it happening from far away before it affects you personally

scale this up using telescopes looking at things super far away
congratulations! the stars, meteors, satellites, debris, comets, planets are like space mexico and earth is like the southern USA

at this much larger scale you get to observe things longer before they happen
space is unironically like a time machine letting you peer into the past and predict the future

ancient civilizations weren't politically correct or brainwashed the same way so they just realize it
mars is an illegal immigrant
if mars gets any closer it will cause problems and we will have to prepare for that


now scale this shit down
you can't predict the bug hitting your windshield at 80mph because it's too close and too small

if space were small it wouldn't let us predict the future
but it's so big it do be like that

I've been working off a SA GTI for the last year and feel like it's time for an upgrade. Still want a portable option since I have to go out of the city to really get dark sky shots. Are harmonic strain wave drives all they're cracked up to be? That seems like the next step up in astrophotography from here.
>>
>>4380710
Really depends on what kind of payload you're planning on, the focal lengths you will be using, and if you want to autoguide. All good equatorials pretty much perform the same if you're not pushing the ratings, have everything properly balanced, and have good alignment. It's all down to the user. Also PEC exists.
>harmonic strain wave drives
Plain old worm drive is trusted.

You didn't give anyone much to go on. But generally speaking, staying under the max rating, proper alignment, and proper balance is top priority so finding ways to achieve that with your current mount may be preferable unless you really do need to upsize. I've gotten proficient with a regular polar scope but think a Polemaster is probably going to be the biggest upgrade I can make to take even longer exposures. Also I'm pretty sure that most people's issues with alignment are from setting up their tripods on soft surfaces like dirt and grass. Mounts on those surfaces will settle for literally weeks, and just walking around them can throw them off. I always set up on exposed granite.
>>
>>4380792
Just using a Zenithstar 61 II with a guide scope for the last year. Frankly, it's enough for me for now. There's enough DSO it can capture that I can spent another year or two trying to shoot on it. I've been thinking if I don't upgrade the mount to something else that I would go for a dedicated astro cam. I've been using a DSLR this entire time. I hear great things about the ASI533MC, but it ain't cheap—definitely cheaper than a new harmonic drive though.
>>
>>4380797
That's a nice setup, and pretty fast. I agree that a dedicated cam would be a massive upgrade but so would a Polemaster, for far cheaper. Just an overall quality of life increase for the whole setup and transferable to other setups you may have in the future.

Since you're focusing on a new drive so much I assume your biggest issue is tracking? I've only ever used 3-star alignment which has worked great, but don't let my scope go over TDC during an exposure... I just assume there's a tiny bit of backlash in the gears. Just a guess though. Seems like good practice in any case. I'll be trying an autoguider for the first time this winter.

There are plenty of affordable harmonic drive mounts out there but they have tiny payloads. I've never used one so can't say much. If tracking is your issue then yeah, your money would be better spent on attaining shorter exposures or something to ensure you're properly polar aligned. I had a lot of issues early on (especially because I was going for planetary with high focal lengths) and they were all solved with proper alignment. I think it's never been perfect though, and am really interested in seeing what a Polemaster will do for me.

Maybe check it out... this dude rushed and fucked up the process several times and still showed great alignment at the end, considering:

Yeah, I've already shot it at 105, 200, 400, and 600mm. I have a reducer for this tube that drops it to ~1700mm, the plan is to not only stack but stitch using the center of the frames with the least field curvature. It will take a few nights and pretty much the point of this little challenge.

Regardless, one of the counterweights is being replaced with the setup mentioned here (homemade astro cam test):

https://archive.palanq.win/p/thread/4154531/#q4166823

Trying to piggyback without adding weight and also taking advantage of the existing weight, basically. Should be good at lower focal lengths... there isn't much flex in the shorter bars and it will be held toward the center. I'm working on a dovetail and aluminum braces to also fix it to the threaded cap since it rotates along with the bar. This way I won't be relying solely on traditional friction locks to prevent it from slipping. The friction locks will just be to aim it initially, then it will get properly tightened down with threads.
>>
Long story short:
>multiple exposures
>stack
>move
>repeat
>stitch stack exports
>resize to 50%
>print
I want a pretty wide shot so it's going to take a while. This is the only reason why I finally ordered an autoguider. Plenty of big stars to use, I already have them chosen. I'll be doing this in the darkest spot in my province over a few trips to keep things as consistent as possible so I won't have time to waste. I've wanted to do this for years but never got around to it.
>>
>>4381823
Why go through all that effort to then shrink 50% and lose all that data? Why not just shoot at 850 mm then?
>>
>>4381827
I can tell you right now that data won't be worth looking at at 100% scale (no amateur astro shot is IMO), it will be better served to scale the image down. The final result will still be a few hundred MP.

It's the sensor that I'm trying to work around. The point here is to reduce but still have a large image with very low noise. I could easily just shoot at 800mm and be done but that's not the goal here. The goal is to experiment and try something different.

That is definitely a failure to keep track during exposure. Question is why?
1 The scope could have been bumped (you'd probably have noticed).
2 A gust of wind resettled the setup.
3 You could have pointed then exposed right away, but a little slop in the gears caused it to 'grab' mid-exposure.
4 The mount may not track quite right.
5 The tripod may have settled during exposure.

Appreciate the prior advice. Pinched lens seems to have been the problem based on threads I have read. Nights have been cloudy so I haven't been able to adjust yet, but that should be coming up in the next few days. using a Zenithstar 61 II, and this appears to be a common problem with WO optics. Plastics in the lens that contract with cold. Will be adjusting some screws out about 1/8 turn and taking samples to see how well the aberration corrects. Hoping to have it solved this week.
