OBSERVATIONAL CAPACITIES OF 1M OPTICAL TELESCOPE ZEISS-1000 AT SAO RAS

Abstract

The optical telescope of SAO RAS Zeiss-1000 saw its rst light of about thirty years ago. Nowadays it is successfully used to solve a wide variety of astrophysical problems. The main observational programs are photometry of bright quasars and nearby Seyfert galaxies, studies of X-ray binaries, monitoring of AGNs, bright supernovae, binary systems, magnetic survey of main sequence
stars, compilation of spectral atlases of bright Ae/Be Herbig stars, studying variability of magnetic peculiar stars etc. We present a brief historical review starting at the time the Zeiss-1000 was manufactured and put into operation. A few words are said about the instruments the telescope was equipped at the beginning and the enhanced ones. Photometric and spectroscopical observational methods realized presently are described in detail. Attention is paid to newly developed devices. When placed in commission they will provide new observational capacities. To raise eectiveness of the Zeiss-1000 operation complex automatization of the telescope control system, update of main mounting components and the telescope optical system adjustment were done. There were increased the telescope pointing accuracy and the tracking quality. The modes of fast-moving celestial bodies' program tracking and of remote observations were realized. The Zeiss-1000 observational time is scheduled and awarded by the Time-Allocation Committee for telescope proposals submitted once a half-year semester
