MASTER: The Mobile Astronomical System of Telescope-Robots

We present the first Russian robot-telescope designed to make prompt observations of gamma-ray bursts (http://observ.pereplet.ru). The telescopes are near Moscow. The system of telescopes with prompt pointing rates connects to the internet. The main parameters are the following: Richter-Slefogt system telescope (355 mm, f/d = 2.4); Richter-Slefogt system telescope (200 mm, f/d = 2.4); Flugge system telescope (280 mm, f/d = 2.5); TV-camera with 20 x 40 degree objective; two CCD cameras (Pictor 416); one CCD Apogee Camera AP16E. The type of mount is German with 8 grad/sec slew rate. MASTER images stars down to 19 magnitude in a 1 min exposure covering 6 square degrees.
