A mirror instead of and objective lens (:
It's important to keep a constant temperature because materials expand or contract depending upon how hot they are. Should one region of the telescope become hotter than the rest, it will change it's shape more, and distort the mirror, reducing the clarity of any images.
all telescopes use a mirror.
The Keck telescope has a 10m mirror.
The resolution is directly proportional to the diameter of the main mirror or lens. For instance, twice the diameter means twice the resolution.

No you cannot. a mirror simply reflects light. you would have to have many mirrors no no
A reflecting telescope.
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).
all telescopes use a mirror.
difference between heat and temperature ..............................mirror formula

Concave means bulging inward - reflecting telescopes use this sort of mirror. The first telescope designed to use one was invented by Isaac Newton and they are therefore called "Newtonian" telescopes.
Concave mirrors are used in telescopes. Convex mirrors are used as side-view mirrors in cars.
There are a variety of places where one can buy a new mirror for a telescope. The best place to get a replacement mirror is at a online shop that sells telescopes.
it is because of the differences between the mirror's temperature and the air's temperature.
