Ground-based solar telescopes are specialized telescopes 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 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.

Space Telescopes
editSolar Space Telescopes are part of the List of heliophysics missions
Other types of solar telescopes
editThere 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[37][38]
Most solar observatories observe optically at visible, UV, and near infrared wavelengths, but other things can be observed.
- CERN Axion Solar Telescope (CAST), looks for solar axions from the early 2000s onwards
- Multi-spectral solar telescope array (MSSTA), a rocket launched payload of UV telescopes in the 1990s
- Leoncito Astronomical Complex, has a submillimeter wavelength solar telescope.
- Razdow Telescope
