Very interesting. It follows my expectation about scopes in general, where I expect scopes in future will only be optical on the front end and electronic on the back end which will eliminate the exit pupil drawbacks at high magnification of purely optical scopes. Once you've gone with a microchip, you can make things sing and dance up to the capabilities of the chip. I've been considering NV for a lark so this sounds like a cheap way to try it and have a fun project along the way (very thorough description by the OP it seems at first glance). I especially like the tie wraps, do they come in camo?
