Catadioptric Telescope

What does the Schmidt, Maksutov and the Cassegrain telescopes have in common?

So much about the refracting telescope and the reflector telescope which I have written extensively here. There is another type of astronomical telescope that is a little bit more complicated than these two. If the refracting telescope employ lenses and eyepieces while the reflecting telescope use mirrors, the catadioptric type of telescope uses both lenses and mirrors to be able to focus the light to the desired object. The Schmidt, maksutov and the cassegrain fall under this telescope category.

The catadioptric telescope is like a combination of both the reflecting and refracting telescopes.

What are the advantages of the catadioptric telescopes?

First, it requires less maintenance.

Also, the designs and parts of the catadioptric telescope are simple and easy to produce.

On the other hand, the disadvantage of this type of telescope is that some of the light that is supposed to enter the tube of the scope is blocked by its supplementary mirror.
