Do I ever need to get together with you to learn.
I did the same thing a few years back with the same intention - showing objects from within the city light dome. I got a GStar Clr and a big TV monitor, and I have to say that I haven't had the same success. OK, but not stunning. I now have a little 3.5" reversing monitor that gives me a better image. I have had some discussions and demos that suggest I might do better with the Gstar capture software (and all its camera and image handling options) on a computer, rather than taking the video signal into a TV.
I'll have to be in touch.
ps, Of course this means I have to have a tracking scope, fairly well aligned. One of my bugbears! I'll try again with the C8 on a wedge.
