Transcript of Parts of the reflecting telescope
It is located at the bottom of the telescope tube. It has a concave shape, which is a half moon-shaped mirror
It is located on the opposite side of the primary mirror.
Eyepiece is used to enlarge the image collected by this mirrors, and it is usually located at the end of the telescope tube at the focal point .
The telescope tube holds the inside-parts of the telescope.
It supports the tube and lets you move it in any direction.
The word telescope comes from the modern latin tele, which means “at a distance”, and scopium, which means “see”; this word was originated in the mid-17th century (Oxford University Press, 2013). The reflecting telescope is used mainly by astronomers to observe celestial bodies in the sky and their features.

Mirrors - cheaper
Lighter than refracting telescopes
No chromatic aberration
Lenses - expensive
Suffer chromatic aberration
