The Maksutov (also called a "Mak") is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical". The negative lens is usually full diameter and placed at the entrance pupil of the telescope (commonly called a "corrector plate" or "meniscus corrector shell"). The design corrects the problems of off-axis aberrations such as coma found in reflecting telescopes while also correcting chromatic aberration. It was patented in 1941 by Russian optician Dmitri Dmitrievich Maksutov. Maksutov based his design on the idea behind the Schmidt camera of using the spherical errors of a negative lens to correct the opposite errors in a spherical primary mirror. The design i

rdfs:comment	El telescopi de Maksutov és un tipus de telescopi catadiòptric o reflector que es caracteritza pel fet que fa servir una lent correctora còncava de menisc negatiu en la pupil d'entrada de l'aparell que corregeix els problemes d'aberració perifèrica presents en els telescopis reflectors. Va ser inventat per l'òptic soviètic el 1941 com una variació del disseny de la càmera de Schmidt. (ca) El telescopio de Maksútov es un tipo de telescopio catadióptrico o reflector que se caracteriza porque emplea una lente correctora cóncava de menisco negativo en la pupila de entrada del aparato que corrige los problemas de aberración periférica presentes en los telescopios reflectores. Fue inventado por el óptico soviético Dmitri Dmítrievich Maksútov en 1941 como una variación del diseño de la cámara de Schmidt. (es) Un télescope de type Maksoutov-Cassegrain est un télescope catadioptrique composé d'un miroir sphérique et d'un ménisque légèrement divergent. La lentille fait généralement le même diamètre que le miroir et est placée à l'entrée du télescope afin de servir de (en) d'aberrations telles le coma et l'aberration chromatique. Ce télescope a été inventé en 1941 par l'opticien soviétique Dmitri Dmitrievitch Maksoutov, qui s'est inspiré du montage de la chambre de Schmidt. Les télescopes de type Maksoutov-Cassegrain se vendent dans le domaine de l'astronomie amateur depuis les années 1950.

Sie findet auch als Tele-Objektiv Verwendung. Das Maksutov-Teleskop wird meist mit Cassegrain-Strahlengang ausgeführt und ähnelt dann dem Schmidt-Cassegrain-Teleskop. Wie dieses hat es einen sphärischen Hauptspiegel, der in der Mitte durchbohrt ist. Seltener finden sich Maksutov-Newton-Teleskope, die vom Newton-Teleskop abgeleitet sind. Das reine Maksutov-Teleskop ist, wie das reine Schmidt-Teleskop, nur als Astrokamera nutzbar, da sich der Fokus im Tubusinneren befindet. Durch die Kombination aus Linsen und Spiegeln handelt es sich um ein katadioptrisches System. Wenngleich dieses Prinzip nach Maksutov benannt wird, wurde es unabhängig von Kurt Penning sowie von Albert Bouw (de) The Maksutov (also called a "Mak") is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical".
