Telescope Magnifying Power

The magnification through a telescope magnifies a viewing object while limiting the field of view.

The subject magnification factor equals the ratio of the objective focal length and the eyepiece focal length.

Formula

QuantityVariable["M", "Unitless"] == QuantityVariable[Subscript["f", "o"], "Length"]/QuantityVariable[Subscript["f", "e"], "Length"]

symbol description physical quantity
M subject magnification factor "Unitless"
fe eyepiece focal length "Length"
fo objective focal length "Length"
