My Celestron C-8 is an 8-inch Schmidt-Cassegrain telescope with a clear aperture of 200 mm and an aperture ratio of f/10 (focal length 2000 mm). For most shots, an intermediate optic reduces the focal length to 1260 mm.

The front lens of the telescope fogs up without the heating ring! That would put an end to the autumn nights!
