How Does a Catadioptric Telescope Work?

Catadioptric Telescopic designs operate with a folded-path optical system, unlike refractors and Newtonian reflecting telescopes

that use a linear optical path. This allows the telescope to be shorter than the size implied by its focal length.

What can you see with a catadioptric telescope?

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.

What are Catadioptric telescopes good for?

Catadioptric telescopes are an excellent choice for astrophotography, but it depends on which kind of astrophotography you're trying to do. Maksutov-Cassegrains are great at planetary imaging, but make for poor deep sky imaging telescopes due to their long focal ratio.
