Re: I/R light source
I should clarify my earlier post.
The reason that I didn't take gmblr seriously is because I do not think the PVS-22 is in its prime anywhere close to 1K. The UNS/PVS-22 will only let you get to around 8X or so with your day scope before you want to claw your eye out and the resolution starts getting pretty rough at several hundred yards even with the Gain turned down.
I.R. in the 400-900nm range will definitely give the unit a boost but the unit itself is still limited at longer distances in most atmospheric conditions.
If one was to seriously want to use NV out to 1k, starting life over with a MUNS/PVS-27 will let you use more X on your day scope, give better resolution and will benefit from any IR augmentation better than the 22. Even 27 is stretching to get there with a lot of resolution on body size targets (ie: is that one target or two standing close together?)
Any focusable IR with a shit load of output would help. The PEQ-2 and 4 are good but there won't be much off the shelf that will net you a noticeable change in image at 1K, especially if you are trying to get there with the 22.
My apologies for coming across possibly a little too smart ass. I am by no means an expert.
