However, if you really want NV device, I am sure you can purchase tubes from military surplus (Surplusshed was selling them, sometimes even ebay).
It is not hard to add power supply and suitable enclosure. |
Though there are different NV devices that can be found amongst military surplus, but for NV to work well for astronomy the best units are required, which means $$$.
The way things stand at the moment, I don't see glass eyepieces becoming obsolete... for now... However give it a couple more decades, or maybe less, of adopting the technology for astronomical use plus a few more years to improve on the products, the end result could be something that may really threaten to shelve glass eyepieces to a bygone era. Like I mentioned before, for this to occur prices will need to come down significantly, the FOV will need to increase, the image will need to appear more natural and be simple enough for anyone to plug in and observe away.

a) Glass won't become obsolete as it still requires an eyepiece for magnification. 
b) it's very expensive for high quality.... prohibitively (like, the cost of a top-tier telescope). And yuo still need the scope (and the eyepieces)
c) also, you don't get colour in NV |
I'm far from being that knowledgeable about NV, but from what I understand you don't necessarily need eyepieces at all for NV, even for magnification. People with NV state that focal length of the telescope is what's most important for image scale with a NV device. Usually barlows and focal reducers are then used to change the image scale for a given telescope.
