Relative aperture of telescope¶
The relative aperture of a telescope is the ratio of the diameter of the lens to its focal length. For visual observations, high-power telescopes give a larger exit pupil size, that is, the picture is bright and clear. A larger field of view allows you to observe extended objects, which include many galaxies and nebulae, that is, objects from Outer Space. In turn, non-high-power telescopes give a greater magnification, other things being equal, and are used in working with objects where details need to be considered, that is, with planets.
