Can you attach a PVS-14 to a telescope? The objective lens has threads (female) and I measure the internal distance to be 29.5mm. I was wondering if there was an adapter out there that would fit these threads and have a 1.25" slip nose on it? Anyone done this or know what I would need?

cnoct, for the non-afocal connection, where did you get the silver part? Did you make it or scavange it from something else? And, how did you attach it to the PVS-5a objective housing? Is it glued or press fit or what?
Okay so I got my parts in today and everything mates up very nicely. You don't have to remove anything from or alter the PVS-14 in any way with the parts I used.
You can use these parts to attach it to an eyepiece or you can attach it to a scope without an eyepiece using a nose cone or just t-thread adapters.
See the pictures. I hope this helps others and I can't wait to try it out. I also have ordered parts for attaching a camera to the other end of the PVS-14 and I'll report back how those work out.

Your afocal imaging setup is really nice and well thought out, great going.
The 2nd method, wherein the PVS-14 replaces the eyepiece, is really intriguing, didn't know it was possible. Once your able to test this method, do post your findings. In the mean time could you explain how this would be an optically compatible option?
If you get the chance, definitely do some prime focus viewing with an image intensified eyepiece/device, by far the best way to use image intensifiers and telescopes.
As far as attaching a camera to the PVS-14's ocular, consider the following if you are using a DSLR/SLR: B&H Photo
If you plan on attaching a point and shoot, then there are a lot of options which I'm sure you'll find the best for your camera and taste.
If your going the iPhone route, then consider some of the following options:
Magnifi or US NightVision. There are other iPhone adapters as well, it comes down to preference.
My preference for attaching a DSLR is either the split ring adapter (pictured and linked above) or the extremely rigid housing adapter, both are pictured below. The latter is not made anymore, at least as far as I know, though you might be able to track some NOS ones.
There are a lot of options for using a PVS-14 in an afocal setup and just as many options for attaching a camera to a PVS-14.
Thank you for showing how your doing it.

Thanks for the complement!
On your question about the PVS replacing the EP, I don't really understand. Are you talking about putting the 1.25" nose cone on it (but that is what you did too)?
I haven't done anything new from what you did, I don't believe. One way attaches the PVS-14 to an EP for afocal viewing/photography and the other way attaches a nose cone for prime viewing/photography.
I have only used the afocal viewing so far (first time last night) and it wasn't all that impressive in my ED80T refractor. I imagine it will be much better in my CPC1100, Orion 10xtg, or Obsession 25" f4.
As far as attaching a camera, I actually ordered the exact part you suggested from B&H Photo as well. I also ordered various step-down rings so that I can get it to mount with variou DSLR lens I have AND the t-threads on my Atik 460ex.
I've got lots of experimenting to do but I am excited. I think this will give me the visual I always wanted, granted, using a large enough aperture.
