The National Science Foundation's Daniel K. Inouye Solar Telescope (DKIST), known as the Advanced Technology Solar Telescope (ATST) until 2013, is a large solar telescope managed by the National Solar Observatory, that is currently under construction. With a planned completion date of 2019, it is expected to become the world's largest solar telescope. It is a collaboration of numerous research institutions.
The telescope will have a 4.0-metre (160 in) diameter primary mirror housed in a large dome, located at Haleakala Observatory on the Hawaiian island of Maui. While still under construction, the telescope was officially named after a US Senator for Hawaii, Daniel K. Inouye.
DKIST features an off-axis, clear aperture design. This avoids a central obstruction, minimizing scattered light when observing the faint solar corona or bright solar disk. It also eases operation of adaptive optics and later image reconstruction such as speckle imaging.
The site on the Haleakala volcano was selected for its clear daytime weather and favourable atmospheric seeing conditions. The DKIST design is intended to enable high-resolution observations of features on the Sun as small as 20 km (10 mi).
The contract to build the telescope was awarded in 2010, with a then-planned completion date of 2017. Physical construction at the DKIST site began in January 2013, and work on the telescope housing was completed in September 2013.
