Abstract:
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.
Description:
The multi-color CCD observations of the NGC 752 area were obtained in
August of 2009 using the Maksutov-type 35/51cm telescope of the
Moletai. Observatory, equipped with a VersArray 1300B CCD camera.
