Morphological Catalogue of Galaxies

The Morphological Catalogue of Galaxies ( MCG short ) is a directory of 29,000 galaxies north of declination -30 °.

The MCG was by Boris Alexandrovich Vorontsov Weljaminow and employees created based on the photographs of the Palomar Observatory Sky Survey ( POSS ). The source names (eg MCG 15-01-001 ) are made up of from the equator projected zone designation of the POSS, with the rising of right ascension box number and a sequential number. The MCG contains coordinates, brightness, size and intensity of the inner and outer regions of the galaxies, as well as references to earlier galaxy catalogs.
