The method of estimation of equatorial coordinates of asteroid on account of his known coordinates in CCD-frame coordinate system is developed, which takes into account dependence of estimation errors of equatorial coordinates on visible brightness of guide stars, and also realizes uniform choice of guide stars on image for increasing accuracy of estimation. By experimental researches on the natural data availability of a method is confirmed precision of the method is defined. The method has used by authors in developed system of automatic online new asteroids detection and known asteroids tracking.
