{{Short description|none}}
Ground-based [[solar telescope]]s are specialized [[telescope]]s used to observe the [[Sun]] from Earth's surface. Solar telescopes often have multiple focal lengths, and use a various combination of mirrors such as [[coelostat]]s, lenses, and tubes for instruments including [[spectrograph]]s, cameras, or [[coronagraph]]s. There are many types of instruments that have been designed to observe Earth's Sun, for example, in the 20th century [[Solar telescope#Solar tower|solar towers]] were common.

There are much smaller commercial and/or amateur telescopes such as ''Coronado Filters'' from founder and designer David Lunt, bought by [[Meade Instruments]] in 2004 and sells SolarMax solar telescopes up to 8 cm<ref>{{Cite web|url=http://www.skyandtelescope.com/news/3309971.html?page=1&c=y|title=Sky & Telescope: David Lunt (1942-2005)|access-date=17 April 2023}}</ref><ref>[http://www.darkskycast.net/davidlunt.html David Lunt biography, Solar Filter designer] {{webarchive|url=https://web.archive.org/web/20110723080442/http://www.darkskycast.net/davidlunt.html |date=2011-07-23 }}</ref>
