Abstract. We describe the astronomical plate archives in Moscow and Zvenigorod and the existing digitization projects. The collection at Sternberg Institute has very valuable parts that can be applied to studies of variable stars and external galaxies and still contain much important information never used yet.

 

 

1 Introduction

 

Regular photographic observations of the sky for variable-star studies were started in Moscow in 1895. Since then, several different telescopes were used to take direct sky plates in and near Moscow, for astrometry and for astrophysics. The Moscow plate archive also contains very important series of direct photographs and objective-prism plates taken at the Sternberg Institute's observatory in Crimea. The direct-plate archive of the Zvenigorod Observatory (Institute of Astronomy of the Russian Academy of Sciences) is less rich but also contains several thousand plates.

 

 

2 The Plate Archive of the Sternberg Institute

 

The contents of the most important Moscow astronomical plate archive, that of the Sternberg Astronomical Institute, was briefly presented in Shugarov et al. [1] in 1999. Since then, the information has been considerably improved. We present its new version in the Table (N is a somewhat rounded number of plates) (In this preprint, the Table was revised compared to the presentation in Sofia and is now still newer compared to [1]). Besides the plate series listed in the Table, the plate archive contains several additional, minor and less important, plate and film series.
