I know you can save money by building your own scope. However, I don'y have the time to grind my own mirror, and am not about to handle a 10 inch, $350 mirror outside of it's cell. Is it possible to create a FrankenScope with a flat primary mirror? Buying a bathroom mirror and getting it coated is alot cheaper. Open for suggestions...

Hey there, Well, a flat mirrors focal point would be infinity, so you'd have to have your focuser kinda far away lol, like infinately far. You would also, even if you could curve a mirror like that to some sort of parabolic curve, have such freaky horrible images it would be unusable. Too bad it would be a cheap way. :-} On the positive note, if you build the scope minus the mirrors, you can buy an 8 inch cheaper mirror and at least get some decent images, Take care! Ron
