Cassegrain Telescopes

A Cassegrain telescope is an optical instrument used for viewing distant celestial objects, consisting of a primary concave mirror and a secondary convex mirror. Light enters the telescope, reflects off the primary mirror, and then off the secondary mirror before reaching the eyepiece. This design allows for a compact and powerful telescope with a long focal length. Cassegrain telescopes are popular among astronomers and astrophotographers for their high magnification and image clarity.
