CCD photometric observations of the clusters M67 and NGC 7790.
Abstract
BVR CCD photometry of the open clusters M67 and NGC 7790 has been performed using 60-cm reflector at Nishi-Harima Astronomical Observatory (NHAO) on Oct. 2 and Dec. 15, 1994. Color equations are obtained for each observation, and compared with those which are obtained by Iyeshima et al. (1994). For M67 the residuals of V magnitudes with the standard stars provided by Gilliland et al. (1991) are also discussed. Moreover the color-magnitude diagram for 49 stars in M67 is drawn up with the obtained color equations.
