A telescope AZT-7 was equipped by Canon 300D. The test observations of comet 17P/Holmes were obtained. With this camera can observe of precision positions of Solar system small bodies until 14.5m-15m if provided of further studies of telescope-camera system, as well as the regulation of the clockwork of telescope and providing with precision time. A correlation between variations of brightness of six bright comets and solar activity level was found. The nonmonotonic changes of comet averaged brightness with solar activity level were found. 2. During 21 nights of reporting period 69 time differences UT0(X)-UTC were obtained. The RMS of these differences determined from group of time stars is 3.87 ms. The error of mean value of these differences during evening is about 2.5 ms. 3. The data for catalogue of absolute proper motions of stars were prepared. 4. The star-substar mass function for population of near solar environment and summary spectrum of massive protostars of Galaxy field was obtained. The results of these researches were partially published, partially prepared for publication and partially are analyzing. These results can be given for all interested organizations and professionals of astrometry, celestial mechanic and star astronomy in Ukraine.
