The NGC Catalog, or New General Catalogue, is a comprehensive list of astronomical objects, including galaxies, nebulae, and star clusters. Compiled by John Louis Emil Dreyer in 1888, it contains over 7,800 entries, each assigned a unique number. The catalog serves as a valuable resource for astronomers and astrophotographers, helping them identify and study various celestial objects. The NGC Catalog is widely used in both professional and amateur astronomy. It provides essential information about the position, brightness, and type of each object, making it easier for researchers to locate and observe them. The catalog has been updated and expanded over the years, but the original NGC remains a cornerstone of astronomical reference.
