Description
With the integration of a 1-meter Cesic primary mirror the GREGOR
telescope pre-commissioning started. This is the first time, that the
entire light path has seen sunlight. The pre-commissioning period
includes testing of the main optics, adaptive optics, cooling system,
and pointing system. This time was also used to install a near-infrared
grating spectro-polarimeter and a 2D-spectropolarimeter for the visible
range as first-light science instruments. As soon as the final 1.5 meter
primary mirror is installed, commissioning will be completed, and an
extended phase of science verification will follow. In the near future,
GREGOR will be equipped with a multi-conjugate adaptive optics system
that is presently under development at KIS.
