Maksutov Telescope 

the general name given to mirrorlens telescopes constructed according to schemes of meniscus systems. Invented by D. D. Maksutov in 1941, the Maksutov telescope usually corrects spherical aberration, chromatic aberration, and coma and, when using a modification of the Piazzi Smyth lens proposed by Maksutov, distortion and curvature of the image field as well. It ensures high-quality images with a field of view up to 5° for an aperture ratio of 1:3. Maksutov telescopes are considerably simpler to construct than the Schmidt mirror-lens telescopes and have a tube approximately half the length. The world’s largest Maksutov telescopes, with menisci measuring up to 700 mm in diameter and mirrors measuring about 1,000 mm in diameter, have been constructed in the USSR and mounted in the Abastumani Astrophysical Observatory (USSR), as well as on top of Mount Cerro Robles (by an expedition of the Academy of Sciences of the USSR in Chile). In the USA the Questar Maksutov telescope has been constructed for amateur astronomers. Maksutov telescopes have become popular among amateur telescope builders in many countries.
