In the Schmidt-Cassegrain design of the Meade 8", 10", 12", 14", and 16" LX200GPS models, light enters from the right, passes through a thin lens with 2-sided aspheric correction ("correcting plate"), proceeds to a spherical primary mirror, and then to a convex secondary mirror.

Schmidt cassegrain telescope diagram

Schmidt telescope - Encyclopedia Britannica Schmidt telescope, also called Schmidt camera, telescope in which a spherical primary mirror receives light that has passed through a thin aspherical lens, called a correcting plate, that compensates for the image distortions—namely, spherical aberrations—produced by the mirror. The Schmidt telescope is thus a catadioptric telescope; i.e., its optics involve both the reflection and ...
