From there, it bounces back down and travels through to an eyepiece or imaging sensor at the back of the telescope. After passing through the corrector, the light strikes the primary mirror and reflects up to the secondary mirror. Although it appears flat to the naked eye, the Schmidt corrector is actually aspherical its glass is figured for hours to achieve the desired shape. Schmidt-Cassegrain telescopes and other “catadioptrics” use mirrors and specialized lenses to shorten the light path, giving them a much more compact design than other telescopes of a similar focal length.įirst, the light passes through the Schmidt corrector lens on the outermost edge of the telescope. Celestron’s versatile, cost-effective design has reigned as a top choice for most amateur astronomers. Since their design was perfected by Celestron founder Tom Johnson in the 1960s, the Schmidt-Cassegrain telescope has been a superior all-around performer for both terrestrial and astronomical viewing as well as astroimaging.
