In optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. High optical power corresponds to short focal length.

WebYou can think of a typical 9×50 finder as one-half of a 50mm binocular. The main advantage of magnifying finders is that they show fainter stars than what can be seen with the naked eye and even some deep-sky objects. A 30mm aperture finder can reach about 1-2 magnitudes deeper than your eyes alone; a 50mm is about 3-4 magnitudes deeper, and ...
