Its optical system consists of a paraboloidal primary mirror of 1.2m diameter and f/3 focal ratio, and a hyperboloidal secondary mirror (31 cm). Both mirrors are made of Zerodur. The telescope final focal ratio is f/13, its field of view is about 40', the image scale is 12.5"/mm.   The telescope has encoders on both axes, and sets to an accuracy of about 1 arcmin over the whole sky. Its mounting is based on modified torque-tube equatorial system. A 516x516 CCD camera is the primary observing instrument of the telescope.     The dome of the 1.2m telescope The primary mirror after the last alluminization (May, 2002)
