Solved example: magnifying power of telescope - Khan Academy

WebA two-lens astronomical refracting telescope is a device that magnifies the images of distant objects by combining two converging lenses one after the other. These two lenses (the objective lens and eyepiece lens) fulfil different roles, and their combination allows us to use telescopes as powerful observation tools. WebA telescope is used to image and magnify a distant object. In its simplest form, a telescope consists of 2 optical elements—an objective and an eyepiece separated by the sum of their focal lengths. These may be either refractive or reflective elements (lenses or mirrors, respectively). While the objective always has positive power, the eyepiece
