GREGOR is a solar telescope, equipped with a 1.5 m primary mirror, [1] located at 2,390 m altitude at the Teide Observatory on Tenerife in the Canary Islands. It replaces the older Gregory Coudé Telescope and was inaugurated on May 21, 2012. [2] [3] First light, using a 1 metre test mirror, was on March 12, 2009 . [4] [5]
GREGOR is the third-largest solar telescope in the world, after the Big Bear Observatory and the McMath-Pierce solar telescope. It is aimed at observing the solar photosphere and chromosphere at visible and infrared wavelengths. GREGOR sports a high-order adaptive optics (AO) system with a 256-actuator deformable mirrors and a 156-subaperture Shack-Hartmann wavefront sensor. Efforts are underway to implement multi-conjugate AO in 2014. [6][ needs update]

Initial astigmatism was fixed during an upgrade with some corrective optics: two off-axis parabolic mirrors. [7]
