I think large schmidt cassegrain telescopes, known as SCT telescopes, are a poor choice for the beginnner in astrophotography. Examples include the meade LX200 and the Cesestron C11 Here are the reasons behind my thinking... One of the most popular varieties of telescope in the modern era is the F10 SCT. These are commonly found in 8, 10 and 12. Schmidt-Cassegrain telescopes, however, are a little different. They use a single external focusing knob attached to an internal mechanism that moves the primary mirror itself, at the back of the tube, to focus the image. This clever scheme has the advantage of keeping most of the focusing mechanism inside the telescope itself, out of harm's way Schmidt Cassegrain Telescopes, or SCTs for short, utilize folded optics to allow for long focal lengths in a compact telescope design. This makes them one of the most compact telescopes per aperture — much shorter than refractors or reflectors of a similar aperture. There are two primary manufacturers of Schmidt Cassegrain Telescopes. Cassegrain telescopes are great optical performers, and offer a variety of designs for any use.
