URL https://en.wikipedia.org/wiki/Optical_telescope Next snippet Related snippets An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct view, or to make a photograph, or to collect data through electronic image sensors. The basic scheme is that the primary light-gathering element, the objective (the convex lens or concave mirror used to gather the incoming light), focuses that light from the distant object to a focal plane where it forms a real image. This image may be recorded or viewed through an eyepiece, which acts like a magnifying glass. The eye then sees an inverted [DISPUTED] magnified virtual image of the object. Most telescope designs produce an inverted image at the focal plane; these are referred to as inverting telescopes. Related snippets (backlinks) Visit also Visit also (backlinks) Flags
