What is the difference in focusing versus magnification power in a microscope and that in binoculars/telescopes? - Quora
The magnifying power of a telescope is the ratio of an object's angular diameter to itsnaked eye diameter. This depends on the focal length of both lenses.Magnification = focal length of objective
