Within the framework of the „Space Situational Awareness Programme“ of the  European Space Agency (ESA) I have the possibility to use remote controlled since 2016 the Schmidt Telescope at Calar Alto (Spain),  formerly known as Large-Hamburg-Schmidt-Telescope. The 0.8m-telescope is provided for observations of Near Earth Objects to predict impacts of asteroids. The Calar Alto Observatory is operated jointly by the Max-Planck-Institut für Astronomie (MPIA) in Heidelberg, Germany, and the Instituto de Astrofísica de Andalucía (CSIC) in Granada, Spain.

Calar Alto Schmidt Teleskop, formerly known as „Großer-Hamburger-Schmidtspiegel“: Diameter of Korrection plate (material UBK 7) Ø = 0.8 m Diameter of Mirror (Material ZK 7) Ø = 1.2 m radius of curvature: 5 m Focal length: 2.4 m    f/3 Construction year: 1954. Manufacturer: Carl Zeiss Jena, Germany. New Mounting for Calar Alto since 1975 from Fa. Grubb-Parsons. SBIG ST-10XME from 2016-12 until 2019-12, Field of View 21.3’x14.3′. FLI ProLine PL230-42 since 2020-01, Field of View 44.0’x44.4′, Pixel Size 1.29″x1.29″. History can be found (in German) here as well as in the book „Sterne über Hamburg“ von Jochen Schramm and here Birkle, Belleman, Elsässer 1994
