Karazin popup.description2 Object of study — stars, extragalactic objects, Solar system bodies, comets. Purpose of work — a finding coordinates of optical components of extragalactic souro sources using the A3T-8 telescope, equiped with CCD-camera, as well as determination of coordinates of Solar system bodies, comets, parameters of Earth rotating, and studing of occultations and eclipses. Method of study — experimental work using astrometrical observation by CCD-camera on A3T-8 and positional observation of stars, Solar system bodies, comets and obtaining and processing the occultations and eclipses data. During the accounting period more than 200 images from the chosen list 608 ERS were received using the A3T-8 telescope with CCD-camera ST-6. Accuracy of observation aproximately corresponds to 0.1" for objects brighter than 18 m. Were received 363 time differences (UTO-UTC)X. Mean-square error of determination of differences (UTO-UTC)X on the time group of stars is equal to ± 0.00395. The processing of positional observations of Solar system bodies was performed: small planets (40 exposures of small planets 532 Gerkulina and 6 Geba in 1996-1997 period); exact positions of comet LINEAR (C/1999 S4) by F.P. Velitsko CCD observations. Were obtained photographic observations of the comet C/1999 H1 (Lee) and small planet 1 Cerera, occultation of stars by the Moon (21 moments of the time). The analysis of observations, which were obtained at the beginning of centennial and their preparation is continued. We studying materials, obtained withs meridian circle in the Kharkov Astronomical Observatory in eightieth years. Observation materials is stored in the digital form in PC. The study of generalised distortion functions for small floors of the 10' x 10' size for the telescope A3T-8 was performed, equation of brightness for Zeiss astrograph of Kharkov Astronomical Observatory was studied.
