Magnification is also sometimes called the power of the binoculars â binoculars labeled as 8-power have eight times magnification. Most optics have clearly labeled magnification, usually on the large focus wheel between the two long barrels of the binns.
Finderscopes usually come with a designation of the form AxB, where A is the magnification and B is the aperture of the finderscope's objective lens in millimeters; for example, a 6Ã30 finderscope means a finderscope with a 30 mm objective and a magnification of 6Ã. This designation is in the same format used by most binoculars. A 6Ã30 finderscope is the minimum useful size for a finderscope on an amateur telescope, and an 8Ã50 or larger finderscope is preferred.
