Digital data processing of 2020 observations was performed, and an astrometric catalogue was derived for 707 thousand stars, which were observed 5 or more times in 315 sky regions around the OSC, which are part of the international WEBDA database (Web version of the database for galactic open clusters "Base Données Amas"). The standard deviation of catalogue positions has a value of ±0.03" for the mean epoch of 2020.6 and for stars with a magnitude of not more than V= 16 mag.
