The way you use a Telescope * Reflector Telescopes an Introduction

Telescopes are of two main types - reflectors telescope and refractors telescope. The fundamental difference between both types is the kind of glasses used for light collection. Refractors use lenses while reflectors use mirrors. Going back to school physics, it is obvious that light from distant bodies, like celestial objects, comes at us as a parallel beam. Due to this parallel nature of the light rays, reflector telescopes use parabolic mirrors.This type of parabolic hand mirror concentrates
