What is a reflecting telescope?

The Basics of a Reflecting Telescope

A reflecting telescope, also known as a Newtonian reflector, is composed of a thick tube with a concave mirror at the rear of the tube and a secondary mirror at the front. The light enters through the tube, hits the concave mirror, bounces to the secondary mirror, and then moves to the eyepiece, which is located at the front of the tube. Astronomy enthusiasts enjoy the reflecting telescope for viewing planets and the moon as well as objects in deep space. Because of its quick focal ratio, which is the photographic speed of a telescope, a reflecting telescope is popular with astrophotographers for producing brilliant images with a short aperture time.
