Vacuum Tower Telescope
From Wikipedia, the free encyclopedia
For the vacuum tower telescope at Sacramento Peak, see Richard B. Dunn Solar Telescope.
The Vacuum Tower Telescope is an evacuated-optics solar telescope located at the Teide Observatory on Tenerife in the Canary Islands. It is operated by the Kiepenheuer Institute of Solar Physics (Kiepenheuer-Institut für Sonnenphysik).
It has a 70 cm diameter primary mirror and a focal length of 46 m. Thanks to an adapative optics system, in operation since spring 2000,[1][2], it is able to resolve details down to 0.2 arc seconds (150 km on the sun's surface).
