More About Cassegrain Telescopes
Cassegrain telescopes (or catadioptric telescopes) offer versatility and high magnifying power. They employ both mirrors and lenses that fold the light path, allowing a compact tube length. Orion Telescopes carries both Schmidt-Cassegrain telescopes and Maksutov-Cassegrain telescopes in a variety of sizes, all of which provide excellent image quality and all-around viewing capability. Both types of Cassegrain telescopes feature a front corrector lens that ensures sharp images. Small Maksutov-Cassegrain telescopes make great grab and go scopes, while Schmidt-Cassegrain telescopes accept a wide variety of accessories for both observing and astrophotography applications.
