The performance of single dish radio antennas or telescopes is depending on the surface accuracy of the reflectors in the beam path and the focus/pointing errors induced by deviations/misalignment of the reflectors from a desired direction. For multi

The optical performance and pointing accuracy of the 1.5 m solar telescope GREGOR depend on the passive and active temperature control design features. Stringent thermal requirements are given in the technical specification for the passive thermal co

Presently the ground-based High Energy Stereoscopic System (H.E.S.S.) with 12 m Cherenkov telescopes is used for very high energy gamma ray astronomy. With these telescopes the Cherenkov light which is generated when cosmic gamma rays are absorbed by

The operational wind speed for the 1.5 m solar telescope GREGOR which will be erected in 2004 on the Spanish island of Tenerife is specified at 20 m/s. At this wind speed the seeing conditions at the telescope site are good for observations of the so

The optical and thermal design of the 1.5 m solar telescope GREGOR is presented. The three first main mirrors of GREGOR will be made from Cesic, a silicon carbide material. One major constraint of large solar telescopes is the thermal load of the str
