—The paper describes Zeiss-1000, the one meter telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS), the history of the development of its observation methods and potential areas of astrophysical research. Detailed attention is paid to instruments and methods of observation which are in service nowadays.
The results of studies of the optics of the 1-m Zeiss-1000 telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS) by the Shack–Hartmann (SH) method are presented. Using a Shack–Hartmann wavefront sensor (SH WFS) we have adjusted the telescope optical system by means of shifts and tilts of the secondary mirror. The procedure has significantly reduced the aberrations that appeared during the long-term instrument operation. A new method to investigate the surface quality of the mirrors of the Zeiss-1000 being applied, characteristics close to the diffraction limit are achieved. In general, the entire opto-mechanical telescope system provides an image quality of about 0.5″ at 80%energy level.
There is the presentation of investigation results of last native elaborations of b/w high sensitive CCD cameras for optical telescope application. By the example of SDU-259 camera (000"Specteletehnika", Moscow) capability of its use as a digitized TV guiding camera for large optical telescopes is demonstrated. In SAO RAS there is constructed SDU-259C camera with termoelectric cooler equipped. The parameters of CCD camera SDU-259C and its test results when used with 10 inch telescope "Meade LXD-55" are given.
There has been created a TV system which is intended for the remote real-time computer control of night cloudness conditions during observations with the optical telescopes of SAO RAS simultaneously all over the sky hemishere at the 6m telescope site neighbourhood. The features of developing such systems are considered. Technical parameters of the system devices program interlaces and the description of operation principle are given.
