Compoundor catadioptrictelescopesare hybridtelescopesthat have a mix of refractor and reflector elements in their design. ... The Schmidttelescopehad a primary mirror at the back of thetelescope, and a glass corrector plate in the front of thetelescopeto remove spherical aberration. These telescopes are also known as catadioptric telescopes. Compound telescopes are optical telescopes that work on the simple principles of reflection. The structure of a compound telescope is fairly simple. A compound telescope has an eyepiece also known as a corrector lens or plate. The concave side of the eyepiece faces the outside. The area around the center of the convex side of the eyepiece is painted into a mirror. This is called the secondary spot. There are primary curved plane mirrors on either side of the opening of the optical tube. Light enters through the upper and lower edges of the eyepiece since they are rays traveling from a long distance. They hit the mirrors and reflect off in such a way that the light lands on the area of the second spot where they get reflected again and the light rays meet at the opening of the optical tube creating a virtual image behind the secondary spot.The plane mirrors are on sliders which allowadjusting for clearer images.

Compound telescopes are also called catadioptric telescopes. These types of telescopes have both a refractor and reflector. The refractor lens is used to form the image. The reflecting lens is curved and the light bounces off of the object. This way it forms an image. With both of these two elements together, it forms the compound telescope.

The light comes into the telescope that goes to the refractor lens that forms the image and then it goes through the refractor lens which is bounces off of the object. Most people may use a simple telescope to observe simple items. However, scientists will use the compound telescope because they need to see a thing either further away or more precise objects.
