The greater the angular magnification M, the larger an object will appear when viewed through a telescope, making more details visible. A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word telescope now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.

Web13 nov. 2014 · There are practical limits of magnification for telescopes. These are determined by the laws of optics and the nature of the human eye.
