GREGOR is the new 1.5 m solar telescope currently assembled on Tenerife, Spain, by the German consortium of the Kiepenheuer-Institut für Sonnenphysik, the Leibniz Institute for Astrophysics Potsdam, the Institut für Astrophysik Göttingen, the Max-Planck-Institut für Sonnensystemforschung and other international partners.
The telescope is designed for high-precision measurements of the magnetic field and the gas motion in the solar photosphere and chromosphere with a resolution of 70 km on the Sun, and for high resolution stellar spectroscopy.
The new Gregory type telescope with open telescope structure, alt-azimuth mount, complete retractable dome, adaptive optics and a pool of well established and new developed post focus instruments will replace the 45 cm Gregory Coudé telescope at the Teide Observatory on Tenerife which will be retired after 40 years of service.
The GREGOR telescope is currently the most import project of the Kiepenheuer-Institute. On 21 May 2012 it was inaugurated and after the follwing science verification it will be one of the most powerful solar telescopes of the world and many new scientific results are expected.
