The plates of the northern sky, received according to the FON program, were scanned in MAO NAS of Ukraine on the Microtek ScanMaker 9800XL TMA and Epson Expression 10000XL scanners. 1600 from them were used for obtaining rectangular coordinates of stars. After an astrometric reduction the catalog of the equatorial coordinates and magnitudes more than 15 million stars was created. Positional and photometric errors of stars (from –2° to 90° on declination) depend, basically, on their positions on plates, the overlap ratio (can reach 8x) and their stellar magnitudes. Estimates of these errors on internal convergence are within the limits of 0.1...0.4" for coordinates and 0.05...0.2m for stellar magnitudes.
