Photometric survey near the main Galactic meridian: 2.2. Finding charts and photoelectricUBVR stellar magnitudes in 26 fields

Finding charts and photoelectric magnitudes of stars in the UBVR system in 26 fields of the MEGA programme are presented. This part of the photometric survey near the Main Galactic Meridian includes the fields with right ascentions 8(h) < alpha < 16(h)30(m) and declinations -2 degrees < delta < 58 degrees. Together with the finding charts of 2.5 degrees x 2.5 degrees the equatorial coordinates of the stars are given for epoch and equinox 1950. Photometric properties of the night sky at the Mount Terskol observatory near Mount Elbrus are derived from the photoelectric observations.
