Question

Describe the working and construction of a Newtonian telescope?

Answer 1

Explanation:

How does a Newtonian reflector telescope work? ... A concave parabolic primary mirror at the back of the telescope collects and focuses incoming light onto a flat secondary (diagonal) mirror that in turn reflects the image out of an opening at the side of the front end of the main tube and into the eyepiece.
