Thanks, I have been reading up on here, apologies as I only just noticed there is a dedicated section for night vision, very interesting reading, perhaps my original post should have gone in there.
Thank you for the replies, I best get doing some more homework.
I read one post, a guy built a setup for under £100 and reckons vision is upto 40 mts. Not bad.
Not convinced I would get on with looking at a screen on top of the scope rather than through the scope, but that's just old habits dying hard I think.
Does anyone know of a night scope, that just fits onto the rear of a day
