GSO 8" RC + DSLR need flatteners?
Let's say I know this guy who is pretty new to all this, and has already spent quite a lot of dough collecting many, too many, bits and pieces. But this guy can't help himself, and is thinking of getting one of the GSO RC scopes. And he has a 40D that he'd like to put on it. He understands that the RC scopes are supposed to be pretty flat field, but is wondering if that applies to all cameras attached to it or just the smaller chip cameras.
And focus is achieved with a normal T adapter on the focuser? No modding or other attachments needed?
