Wide Field CCD Photometry of the Open Cluster NGC 752
Abstract
The results of CCD photometry in the seven-color Vilnius system of 3058 stars down to V ∼ 18.0 mag in a 1.5 square degree field around the cluster NGC 752 are presented. For most of the stars brighter than V = 17.0 mag, photometric spectral and luminosity classes are determined. The catalog of 1174 stars down to V = 15.5 mag is given in the paper. The entire catalog will be available at the CDS Simbad database. The color-magnitude diagram indicates an extension of the cluster's main sequence down to 5 mag below the turnoff point.
