So is it f2.8, f2.9 or f3.0? I look on their website and I see 200mm aperture + 600mm focal length, which is f3.0. Then on a caption I see f2.9, then in the title it says f2.8
Re the Celestron/Epoch I bet there are a few still around. I wonder how easy it would be to get one to work with a field flattener + CCD?
