GREGOR Solar Telescope

The 1.5 m solar telescope GREGOR was built at the Observatorio del Teide by a German consortium led by the Leibniz-Institut for Solar Physics (KIS), with the Leibniz-Institut für Astrophysik Potsdam, the Max-Planck-Institut für Sonnensystemforschung Lindau and the Institut für Astrophysik Göttingen (until 2008) as partners. The Instituto de Astrofísica de Canarias and the Astromomical Institute of the Academy of Sciences of the Czech Republic contributed to the telescope or the instrumentation. Since 2014 GREGOR is used for scientific observations. 

GREGOR is the largest solar telescope in Europe. It is designed for observations of the solar photosphere and chromosphere in the visible and near infrared.


The -> Scientific Instrumentation includes BBI, GRIS, GFPI, BIC/HIFI, and ZIMPOL. GREGOR is equipped with a high-order adaptive optics system.
