The Swedish 1-m Solar Telescope is a refracting solar telescope at Roque de los Muchachos Observatory, La Palma in the Canary Islands. It is run by the Institute for Solar Physics of Stockholm University. The primary element is a single fused silica lens, making it the largest optical refracting telescope in use in the world. The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically larger than Yerkes Observatory, only 39 inches are clear for the aperture. The SST is most often used as a Schupmann telescope, thereby correcting the chromatic aberrations of the singlet primary.

Konkoly Observatory is an astronomical observatory located in Budapest, Hungary is part of the Research Centre for Astronomy and Earth Sciences and belongs to the HUN-REN Magyar Kutatási Hálózat. Konkoly Observatory was founded in 1871 by Hungarian astronomer Miklós Konkoly-Thege (1842–1916) as a private observatory, and was donated to the state in 1899. Konkoly Observatory, officially known as HUN-REN CSFK Konkoly Thege Miklós Csillagászati Intézet in Hungarian, is the largest astronomical research institute in Hungary, and hosts the largest telescopes in the country. The Observatory has more than 60 researchers, a quarter of them are non-Hungarian.
A solar telescope or a solar observatory is a special-purpose telescope used to observe the Sun. Solar telescopes usually detect light with wavelengths in, or not far outside, the visible spectrum. Obsolete names for Sun telescopes include heliograph and photoheliograph.
The Daniel K. Inouye Solar Telescope (DKIST) is a scientific facility for studies of the Sun at Haleakala Observatory on the Hawaiian island of Maui. Known as the Advanced Technology Solar Telescope (ATST) until 2013, it was named after Daniel K. Inouye, a US Senator for Hawaii. It is the world's largest solar telescope, with a 4-meter aperture. The DKIST is funded by National Science Foundation and managed by the National Solar Observatory. The total project cost is $344.13 million. It is a collaboration of numerous research institutions. Some test images were released in January 2020. The end of construction and transition into scientific observations was announced in November 2021.
The Shamakhy Astrophysical Observatory, named after Nasreddin Tusi of the National Academy of Sciences of Azerbaijan was established on November 17, 1959, by decree No. 975 of the Council of Ministers of the Azerbaijan SSR. ShAO operates as a research institute within the ANAS Department of Physical, Mathematical, and Technical Sciences. The Observatory is located in the north-east of the Greater Caucasus Range, 150 km from the city of Baku, in the eastern part of Mount Pirkuli, at an altitude of 1435–1500 m above sea level, in geographical coordinates λ = 48⁰ 35' 04" E, φ = 40⁰ 46 '20"N. Here the number of clear nights suitable for observation reaches 150-180 per year.
Leibniz Institute for Astrophysics Potsdam (AIP) is a German research institute. It is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory Potsdam (AOP) founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. The AIP was founded in 1992, in a re-structuring following the German reunification.
Interface Region Imaging Spectrograph (IRIS), also called Explorer 94 and SMEX-12, is a NASA solar observation satellite. The mission was funded through the Small Explorer program to investigate the physical conditions of the solar limb, particularly the interface region made up of the chromosphere and transition region. The spacecraft consists of a satellite bus and spectrometer built by the Lockheed Martin Solar and Astrophysics Laboratory (LMSAL), and a telescope provided by the Smithsonian Astrophysical Observatory (SAO). IRIS is operated by LMSAL and NASA's Ames Research Center.
