Sadly no stars tonight, but here's one down my street from my driveway. The pvs14 I got has really good resolution that's being lost somewhere along the way, I'm trying to fine tune the focus. I suspect I may need to cut another thread adapter that puts the eye piece closer to the camera's lens.

That's significantly better than I expected
cool shit.

Why connect it to a lens, instead of approximating focal distance and attaching it to a cheap chinese helicoid by adapter or something? You're adding layers of transmission that aren't necessary.

>>4300057
> helicoid
by the looks of it I'd still need a thread adapter assembly to go pvs14 30mm -> male-threads -> helicoid -> camera. Unclear if this would get me a clearer picture or not.
One of the tricks to getting a better shot thus far was closing the aperture on the lens to 5.6 or 8 and setting lens focus to infinite.
Would I adjust the diopter value to change focus?

>>4300041
you might not be getting sharp photos vecause of the minimum focus distance of the camera lens

you need to try a macro lens with a very close focus distance

>>4300114
The focus is set to infinity, I'm trying to focus through the eye piece, not at its surface. Its working fairly well but more experimentation is needed. I'lll see what happens if I bring the pvs14 closer to the lens without the added lens assembly, and I'll try to bring the pvs14 closer to the sensor without the lens at all.

>>4300105
>diopter value
Presumably. I'm no expert on optics. I asked because I've fucked around with unconventional adapted imaging before and my general understanding is that more glass/apertures/etc. that affect transmission, the more optical degradation you'll have. Eliminating the lens might increase image fidelity.

>>4300571
What I would do is figure out the approximate flange focal distance of the eye. Very likely a camera's flange focal distance is greater. That means you might need to remove the eyepiece to get the cam closer.

>>4300041
Nice idea anon, post moar

>>4300042
Cute

cool shiznit anon.

>>4300572
I fiddled around with the pvs14 and the bare 50mm lens without the thread adapter. I got best results when the pvs14 was closest to the 50mm lens. I took my thread adapters to the lathe and took off about 4mm worth of threads. Now I can run aperture f/2.0 and focus at infinity.
Diopter value was critical. For my eye it works best between 0 and -0.5, for the 50mm lens it works best at +0.5
This pvs14 has a FOM of 2600+ and 81 lp/mm so its absurdly sharp to my eye. I wish the diopter had a fine-tuning method so I could achieve that with the lens.
No clouds, let me see if I can grab some star shots.

turns out stars are exceedingly tough to get a good shot. the screen is dark enough to make the camera crank up the ISO.

I live on the outskirts of a city, so there's still enough light that I can see maybe 100 stars with my eyes. With the PVS14 I can see at least 100x as many.
This is with the exposure running -1.7 to force the camera to a lower ISO and show it closer to what my eyes see. Without this it washes out a lot.
So many stars.
For those that have never looked into the heavens with a PVS14, find a way and do it. So worth it.

>>4300739
I like it.

>>4300042
bro you need to white balance ur images what the fuck
so cyan/green

>>4300041
great idea. try using some filters on the front of the nvd and male b&w then single channel, combine to make false color image

>>4301292
shut up, retard.

>>4301318
>combine to make false color image
beyond my skill set, but sounds interesting.

>>4301825
>beyond my skill set
The hardest part is getting the red/green/blue filters between the camera and NVG while keeping the distance the same otherwise it's as easy as taking the same picture 3 times.

>>4301827
idk maybe it should go in front of the nvg i'm drunk

>>4301830
No, that's not how electro optics work.
any filter will just reduce the amount of incoming light and will have no effect on the output color.
output color will always have that white phosphor tint.

>>4301827
>>4301830
>>4301863
Yes it needs to go in front of the NV, and yes it will affect the output image. You won't get a different coloured output but the resulting image will be filtered and could then be converted to that colour.

>let me put colored filters
>in front of something that amplifies largely infrared light
you really are this retarded arent you

>>4301876
Not retarded but I'll admit that I don't know enough about the electromagnetic spectrum to say for certain. My assumption was that while they do amplify only infrared light, that light is bouncing of objects that have a "colour" and so a coloured filter would affect what is captured. Thinking about it again you would be right because the filter would only be filtering out visible light of that colour.

Would there not be a way to determine the colour of objects using specialise infrared filters though? Like do objects of a certain visible colour not reflect infrared light of a certain frequency?

>>4301876
Yes, I am retarded. Problem?

>>4301868
jesus dude, you are a retard.
I can tell you've never owned a PVS14.

>>4301898
Things that are about same colour in visible light can reflect NIR very differently and vice versa. It's not about visible colour but composition of the reflecting surface. There is a thing called IR spectroscopy for identifying chemical substances.

>>4301876
Gen 3 nods see enough of the visible spectrum to form a color image from three RGB filtered shots. However, to get color comparable to what we're used to you would also need to filter IR. If you left the IR it would be like an extreme IR color photo from a converted digital sensor. More extreme than a SiOnyx Aurora (webm related).

Were you the anon who asked about how to do this a while back? I remember directing someone to k/nvg/ for all the info.

In any case, nice shots anon. Fucking love nods.

>>4301982
>Were you the anon who asked about how to do this a while back?
Yes! thank you for sending me that way and for your encouragement. It all came together when I made my own 43mm thread adapter and adjusted the diopter.
and I totally agree these things are amazing, the PVS14 truly is a magic device.
