Thermal characteristics of the solar telescope GREGOR

R. Volkmer

Open publisher page 9 citations

Abstract

The solar telescope GREGOR is under construction on the canary island Tenerife. A large effort was made to thermally characterize the telescope during the design phase. The image quality is very sensitive to differences between ambient and structure or main mirror temperatures. Tests with the GREGOR telescope structure and an integrated dummy mirror were made to investigate the distribution and temporal behavior of the temperature of the telescope and main mirror.
