The revised new general catalogue of nonstellar astronomical objects

This book is an updated version of J.L.E. Dreyer's New General Catalogue of Nebulae and Clusters of Stars (1864). In producing this much-needed work, the authors have greatly revised, corrected, and enlarged the following useful information for each entry: NGC identification number; type of object on the Palomar Sky Survey; magnitude of object; source of magnitude; visual appearance of object transcribed from Dreyer; Palomar Sky Survey description of each object; and cross references for RNGC objects.Published 1973.
