Haertig... I've been considering obtaining some Night Vision equipment for a couple of years, but decided against it... my neighborhood has a lot of large overhang trees, privacy fences, relative close houses, and no real clear lanes of vision except for the road way..I live on the corner so I have 4 directions to observe... I have been testing the light gathering ability of my inexpensive Tasco binoculars under normal street light... 7x35 and 12x50, with a 5mm and 4.2mm exit pupil diameters... the slight numerical difference does make my 7x35 slightly better, and the lower power gives me a much better sense of distance at night...

both of my black rifles have Trijicon 4x42 ACOGS and have excellent 8mm exit pupils...

I even added a light mount off the binoculars that hold a P60 high intensity light..

you might want to see how well your long range scopes do as to gathering light, just in case... regards
