      Description:

      Maksutov-Cassegrain Telescope Named after Russian optician Dmitri Maksutov (1896-1964), the Maksutov telescope is a type of Cassegrain reflecting telescope that uses a spherical primary mirror in conjunction with a meniscus-shaped correcting plate at the entrance pupil in order to correct for spherical aberration. It differs from the similar Schmidt-Cassegrain telescope design in that the meniscus-shaped corrector plate allows for the use of an easily fabricated spherical secondary mirror rather than the hyperbolic mirror required for the Schmidt telescope. The Maksutov design also has excellent correction for off-axis aberrations such as coma, which is a significant problem in the simpler Newtonian reflecting telescope. In some configurations, the Maksutov secondary mirror can be generated by simply silvering the central portion of the inner surface of the corrector plate. In this type of configuration, the Maksutov design has been mass-marketed as an inexpensive, very compact small-aperture telescope by several major manufacturers. The chief disadvantage of the Maksutov design is that it does not scale up well to even moderate apertures (>200mm), since the corrector plate rapidly becomes prohibitively large and heavy as the aperture increases.
      Maksutov-Cassegrain A catadioptric telescope that uses a thick and deeply-dished spherical corrector lens to correct for the spherical aberration of its spherical primary mirror - an all-spherical design that keeps its collimation virtually indefinitely. Its typically long focal ratio and small secondary obstruction yield higher contrast and resolution than any other catadioptric or reflector design

         Great Scope!, October 23, 2014 ( FEATURED REVIEW )
        This scope gives incredible views. I haven\'t noticed any extra color, even on bright objects. I have viewed inside and outside the solar system and have been amazed at all the views. This is now my favorite scope that I own. It\'s ready to go at a moments notice, no collimation, minor setup and you are viewing. Saturn\'s rings are no problem, Jupiter\'s moons, easy. The mount is extremely stable. I can\'t say enough about this scope.
