Description

The Newtonian telescope is a kind of reflecting telescope that uses a diagonal mirror to reflect light out the side of the telescope. Thus, the eyepiece is positioned at the side of the telescope. This design is usually used in smaller telescopes. A Cassegrain telescope is a kind of reflecting telescope where a secondary mirror reflects light back through a hole in the primary mirror`s center.
