The Celestron distinguishes itself as the best telescope for astrophotography for the money.

Obviously the wider your aperture is the more light your sensor collects, but by shooting with your aperture wide open you decrease depth of field, and run the risk of losing image quality. This lens is famous for its amazing dramatic effects. The maximum diameter of the lens is 87mm.
