    Comparison of nominal sizes of apertures of LAMOST (in red) and some notable optical telescopes. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guo Shoujing Telescope (Chinese: 郭守敬望远镜) after the 13th-century Chinese astronomer, [1] is a meridian reflecting Schmidt telescope, located in Xinglong Station, Hebei Province, China.

    en.wikipedia.org/wiki/Optical_telescope

    The Large Binocular Telescope at the Mount Graham International Observatory in Arizona uses two curved mirrors to gather light. 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 visual inspection, to make a photograph, or to collect data through electronic image sensors.

    Field lens: A correcting lens placed just before the image plane of a telescope. [citation needed] Telecompressor or focal reducer: Optical element to decrease the telescope's focal length and magnification (usually by a fixed percentage) and widen the field of view, providing opposite effects of a Barlow lens.

    There are always more telescopes (Spitzer, Sloan Digital Sky Survey, Pan-STARRS, solar telescopes, notable historical ones like Herschel's 40-foot telescope and the Leviathan of Parsonstown), but you have a good assortment and I don't want to clutter the diagram more. The focus seems to be showing the upcoming generation of extremely large ...

    A diagram of the electromagnetic spectrum with the Earth's atmospheric transmittance (or opacity) and the types of telescopes used to image parts of the spectrum. Visible-light astronomy encompasses a wide variety of astronomical observation via telescopes that are sensitive in the range of visible light (optical telescopes).

    The first two telescopes, the Vatican Advanced Technology Telescope and the Heinrich Hertz Submillimeter Telescope began operations in 1993. The Large Binocular Telescope , one of the world's largest and most powerful optical telescopes, began operations using mirrors independently in 2004, with joint operations between the two mirrors ...

    en.wikipedia.org/wiki/Schmidt_camera

    In 1977 at Yerkes Observatory, a small Schmidt telescope was used to derive an accurate optical position for the planetary nebula NGC 7027 to allow comparison between photographs and radio maps of the object. [17] Starting in the early 1970s, Celestron marketed an 8-inch Schmidt camera. The camera was focused in the factory and was made of ...
