I made this video on a night with 0% moon, and only partial starlight. I did so to show people that night vision does have limitations, even on "clear" (not rainy) nights, without supplemental illumination. It does not "allow you to see in the dark", it "amplifies available light to allow you to better resolve images". This particular PVS14 has an L3 filmless tube with the following specs:
35.7SNR
0.5 EBI
0.7 Halo
2531 photocathode response
64348 gain
zero blems/spots greater than 0.003" in Z1,2,3, no FPN
Filming notes:
The video was made with the manual gain turned up all the way for filming purposes. A LIF filter was in place over the objective, as was a mil-spec de-mist shield over the ocular. A Samsung S8 was left on "auto" for this filming. The images look true to my eyes, but keep in mind your phone or PC will enlarge the video images in size, which will degrade image quality. A PVS14 is worn very near the eye, and has a much smaller "screen", so in-person resolution is significantly better. Viewing this on a cell phone held at normal viewing distance will give a similar perception of image resolution as I experienced with my naked eye in front of the PVS14.
