Both SCT and Mak-Cass have the eyepiece exiting the back of the telescope. A Maksutov-Cassegrain telescope (Mak-Cass) uses a thick and heavy corrector plate with a convex secondary with a spherical primary mirror. A Schmidt-Cassegrain Telescope (SCT) uses a spherical primary mirror, a convex secondary mirror, and a corrector plate that corrects spherical aberration.
Compound – A combination of front lens and primary mirror, often with a pair of secondary mirrors.Refractor – Two or more lenses focusing light straight through the tube to an eyepiece, often with a secondary mirror that makes the viewing more comfortable.Reflector – A concave mirror at the back of the scope focusing light, often to a secondary mirror that reflects light to the eyepiece.Telescope Types – Reflector, Refractor, & Compound From Sky & Telescope Magazine Ask questions, do your research, and make informed purchase decisions. We do not have a relationship with any of the vendors or manufacturers. Please note that I’ve provided links to vendors, but this is only to provide examples of scope types. I’ll list additional resources at the end. I’ll give a quick summary of scope types, but please note, this is far from comprehensive. We’ll be glad to answer your questions, show our telescopes, and guide you in your choices. Your best bet is to join our public star parties and ask our members about our telescopes.
I wouldn’t recommend a super car when you live on a ranch and I wouldn’t want to recommend a large scope if you don’t have space to store it.
