Answer:
A reflecting telescope generally consists of a primary mirror, a secondary mirror, and an eyepiece. Different types of reflecting telescopes use different arrangements of these three components and may add other components such as lenses.
Most refracting telescopes use two main lenses. The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens.
Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. ... To do that, the optics—be they mirrors or lenses—have to be really big. The bigger the mirrors or lenses, the more light the telescope can gather.
