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.
