List of solar telescopes

This is a list of solar telescopes built in various countries around the world. A solar telescope is a specialized telescope that is used to observe the Sun.
This list contains ground-based professional observatory telescopes at optical wavelengths in chronological order. Solar telescopes often have multiple focal lengths, and use a various combination of mirrors such as coelostats, lenses, and tubes for instruments including spectrographs, cameras, or coronagraphs. There are many types of instruments that have been designed to observe Earth's Sun, for example, in the 20th century solar towers were common.
Former solar telescopes after 1900.
Telescopes for the Sun have existed for hundreds of years, this list is not complete and only goes back to 1900.
Other types of solar telescopes.
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
Most solar observatories observe optically at visible, UV, and near infrared wavelengths, but other things can be observed.
