The Daniel K. Inouye Solar Telescope (DKIST), formerly Advanced Technology Solar Telescope (ATST), is a large domed[1] solar telescope facility that is under construction[2] by the National Solar Observatory atop the Haleakala volcano on the Pacific island of Maui. The telescope was officially named after Daniel K. Inouye on Dec 15, 2013.
DKIST features an off-axis, clear aperture design to allow for observations with unprecedented spatial, spectral and temporal resolution. Avoiding a central obstruction is important to minimize scattered light when observing the faint solar corona, but it also eases operation of adaptive optics and post-facto image reconstruction such as speckle imaging.
The site on Haleakala was selected for its clear daytime atmospheric seeing conditions, which will enable study of the solar corona. The DKIST enclosure will house a 4-meter diameter solar telescope capable of observing objects on the Sun that are 30 km across.
Work on the telescope housing was reported complete in September, 2013.[3]
