The Morphological Catalogue of Galaxies (MCG)[1] or Morfologiceskij Katalog Galaktik, is a Russian catalogue of 30642 galaxies compiled by Boris Vorontsov-Velyaminov and V. P. Arkhipova. It is based on a close scrutiny of prints of the Palomar Sky Survey plates, and putatively complete to a photographic magnitude of 15. Including galaxies to magnitude 16 would have resulted in an unmanageably large dataset. [2]
