Telescope-Computerized Telescopes-Celestron CGEM II 700 Mak – 7″ Maksutov-Cassegrain Telescope on CGEM II Computerized Equatorial Mount

The Maksutov-Cassegrain Optical Design
The Maksutov-Cassegrain, often referred to as a “Mak”, is a type of catadioptric telescope, meaning it’s furnished with both a lens and mirror. As opposed to a Schmidt-Cassegrain telescope, a Mak utilizes a “secondary spot” in lieu of a secondary mirror. This secondary spot is a highly reflective coating applied within the corrector lens, and is much smaller than the secondary mirrors found within SCTs. This means more light is able to reach the primary mirror for brighter, higher contrast views! Another bonus, collimation is not required as frequently as seen with SCTs. Something to note, the thicker corrector lens found within Maks have a slower time adjusting to the ambient air temperature than SCTs of the same size aperture. With this in mind, taking the time to fully acclimate your telescope to the surrounding temperature results in the best possible user experience. With its focal length of 2700mm and f/15 focal ratio, this telescope design was specialized for capturing small celestial objects, such as the planets, the craters on our Moon, and deep sky objects like planetary nebulae and globular clusters. Also, this Mak is equipped with the Celestron StarBright XLT coatings to maximize light transmission to the eyepiece or camera for sights with unrivaled clarity!
