We present BV photometry of the Galactic globular cluster NGC 6402 (M14),based on 65 V frames and 67 B frames, reaching two magnitudes below theturn-off level. This represents, to the best of our knowledge, the deepestcolor-magnitude diagram (CMD) of NGC 6402 available in the literature....
We present CCD surface photometry for four globular clusters: NGC 2298, NGC 6402, NGC 6934 and NGC 7089. Our photometry was aimed at the central 3 arcmin region in each cluster. We show that the surface brightness distributions of these clusters are well described by the isothermal King (196...
