The Digitized First Byurakan Survey (DFBS) is the digitized version of the famous Markarian survey plates. A few thousand important objects were discovered by means of this database, including the Markarian galaxies, quasars, cataclysmic variables, white dwarfs, carbon stars, etc. Optical identifications for some 1500 IRAS sources have been carried out as well. The DFBS plates were taken in 1965-1980, thus giving additional chance to investigate the high-galactic regions of the northern sky for proper motions, variability, and roughly classify large number of objects in the given area. The astrometric and photometric accuracy of the DFBS plates were proven during the tests of the astrometric solution and photometric consistency. Thus, the DFBS spectra and the derived O and E magnitudes can be used together with the DSS1 and DSS2 for variability studies in a large area (17,000 sq. deg.). A search for proper motion stars and variable objects (both galactic and extragalactic) has been started using the DFBS.
