Аннотация:Most of our UBV(RI)C CCD observations were taken with the SBIG ST10-XME camera mounted in the Newton focus of the 0.5m (f/5) reflector at the Stara Lesna Observatory. Further CCD observations were taken with the Apogee-47p and Pictor-416 cameras mounted in the Cassegrain focus of the 0.6m (f/12.5) reflector and 0.5m Maksutov (f/4.0) telescope at the Crimean Laboratory of the Sternberg Astronomical Institute. We also used the 0.6m telescope Zeiss-600 of the Terskol Observatory (in Caucasus) equipped with a CCD camera (the PixelVision Vienna with a 1024x1024 array and pixel size 24 micron).
