Barnard Catalogue

The astronomer Edward Emerson Barnard compiled a list of dark nebulae known as the Barnard Catalogue of Dark Markings in the Sky, or the Barnard Catalogue for short. The nebulae listed by Barnard have become known as Barnard objects.[1] A 1919 version of the catalogue listed 182 nebulae;[2] by the time of the 1927 version, it listed 369.[3]
