Question

2) What is the magnification of a telescope​

Answer 1

Answer:

practice it is considered to be 2× the aperture in millimetres or 50× the aperture in inches; so, a 60mm diameter telescope has a maximum usable magnification of 120×.

Answer 2

Explanation:

Most of us know how to compute the visual magnification of our telescope when using an eyepiece: Divide the focal length of the telescope by the focal length of the eyepiece. For example, a 1,000-mm telescope with a 20-mm eyepiece gives a relative magnification to our eye of 50× when looking through the eyepiece.
