What is the purpose of catadioptric?
Catadioptric telescopes are optical telescopes that combine specifically shaped mirrors and lenses to form an image. This is usually done so that the telescope can have an overall greater degree of error correction than their all-lens or all-mirror counterparts, with a consequently wider aberration-free field of view.
How does the catadioptric telescope?
It works by the generation of a vacuum on one end of the plate and accurately adjusting for rectifying the spherical aberration generated by the spherical primary mirror. Amateur astronomers widely use these telescopes.
Where are Catadioptric telescopes used?
The catadioptric Astrograph is a telescope designed for doing astrophotography rather than visual observing. In amateur astronomy Astrographs are used mostly for obtaining images of various objects, but they also have been used for doing sky surveys as well as searching for comets or asteroids.

Did Canon make a mirror lens?
A Canon 1200mm f/8 IS mirror lens design. A Canon 2000mm f/15 IS mirror lens design.
What is the difference between a Cassegrain and a Schmidt Cassegrain telescope?
The main difference between Schmidt-Cassegrains and Maksutov-Cassegrains is the corrector lens at the front of the telescope. Both scopes use spherical mirrors which induce spherical aberration.
Are mirror lenses good?
A big advantage of mirror lenses is that, due to their design, image files produced by mirror lenses are free from chromatic and off-axis aberrations, which are common with traditional refractive telephoto lenses. A traditional 600mm lens and a 500mm mirror lens side-by-side.
