Abstract:
The CCD observations of a sky area in the NGC 6913 cluster were
performed with the 2-meter telescope of the Terskol Peak Observatory
(Northern Caucasus, Russian Federation). The magnitudes and
coordinates of stars down to V=20mag were determined for a 7'x5'
field. The equatorial coordinates of stars were obtained in the
reference system of the USNO A2.0 catalog (Cat. I/252) with an
accuracy of 0.35". The relationship between the instrumental
photometric system and the Johnson UBVR system was derived.
