The results of CCD photometry in the seven-color Vilnius system of 3058 stars down to V~18.0mag in a 1.5 square degree field around the cluster NGC752 are presented. For most of the stars brighter than V=17.0mag, photometric spectral and luminosity classes are determined. The catalog of 1174 stars down to V=15.5mag 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 5mag below the turnoff point.
