Using the Cassegrain focus of the 0.7 m telescope, the pointing and tracking systems of the telescope were developed and tested for laser communication experiments with the unstable geostationary satellite ARTEMIS ESA (fluctuation of the position is more than ±7.2°). The systems allow one to find unstable geostationary satellites, comets and asteroids up to 18m and to perform the tracking of the ARTEMIS satellite with the root mean square deviation 0.68 arcsec by hour angle and 0.34 arcsec by declination.
