The study reports visual and photographic measures listed for 1150 pairs obtained in the time frame 1989.91-1992.15, including 221 new double stars. Magnitudes were estimated for a part of the objects, especially the fainter ones. Plate orientations were calculated from field stars of known positions and were precessed to the epoch; numbers of nights and of measured exposures are given. Reobservation of faint, neglected pairs reveal many corrections to the data from the old discovery lists.
