TitleThe 1.5 m GREGOR Solar Telescope
AuthorsThomas Berkefeld
AbstractWe give an overview of the 1.5m GREGOR solar telescope including current results and we present future developments. GREGOR is an open-dome Gregory-type telescope run by German Insitutes on the Island of Tenerife, Spain. It features state-of the art postfocus instrumentation including a solar adaptive optics system which provides - in conjunction with postprocessing - diffraction-limited observing from 390nm to 1600nm. Current developments will expand the two-dimensional spectro-polarimeter (Fabry-Perot) setup, add more (simultaneous) wavelength measurements to the spectrograph and complement the adaptive optics with night-time and solar off-limb (prominence) locking.
