Fun facts
Stellar objects are at an infinite distance. As you studied in earlier classes, when an object is placed at an infinite distance from the concave mirror, the image formed by a concave mirror would be diminished and inverted. Yet, astronomical telescopes use concave mirrors.
At the right, light enters the telescope and travels to a concave mirror. The light is then reflected back to the eyepiece and eye from the back of the telescope. The primary goal of the Reflector is to focus the incoming light using a concave mirror.
