    CCD photometry of the metal-rich halo cluster NGC 6366.
    We present new BV photometry for 6564 stars in the field of the globular cluster NGC 6366, using a wide field CCD camera at the prime focus of the Isaac Newton...

    CCD Surface Photometry of Southern Galaxies in BVRI
    ABSTRACT: B, V, R, and I CCD frames were obtained for the Southern Galaxies NGC 5757, and IC 1091. The frames were analysed to derive standard photometric and...
