MODERNIZATION OF AZT-22 TELESCOPE OF MAIDANAK HIGH-ALTITUDE OBSERVATORY: TESTING RESULTS

Abstract

The AZT-22 telescope, equipped with the ML09000-65 CCD camera, has shown to be capable of obtaining high-quality images of astronomical objects and thus solving a wide range of observational tasks. Diffraction-limited telescope optics together with the excellent seeing conditions at Mt. Maidanak Observatory allows recording images with the seeing quality better than 0.6 arcsec. The accuracy of differential photometry for an isolated star is 0.002 stellar magnitude. Automatic guiding system of the telescope provides obtaining long exposures with reliable recording of objects down to 24 stellar magnitude.
