A telescope is an optical instrument that allows you to observe distant objects and magnify their image. The magnification of binoculars usually ranges from 20x to more than 200x. However, higher magnification does not always mean better observation, as high magnification can cause an uneasy image and reduced image quality. In addition, to achieve high magnification, the binoculars must be placed on a stable base to minimize hand shaking. Binocular magnification typically ranges from 20x to over 200x.
