Deep CCD photometry of stars in the globular cluster M3
CCD photometry of faint stars in the globular cluster M3 is presented. The observations reach down to V equal to about 23 mag, with a sample of approximately 5000 stars. The resulting color magnitude diagram has a turn-off significantly redder than those obtained in previous studies. Age and distance are derived by fitting the observed mean line to
