General Catalogue

From Wikipedia, the free encyclopedia

The General Catalogue of Nebulae and Clusters was published in 1864 by John Herschel. It was combined with other observations to produce the New General Catalogue in the 1880s by J. L. E. Dreyer. The GC catalogued nebulae, contained 5,000 entries, half of the observations by father William Herschel, half by son John. Later, a complementary edition of the catalog was published posthumously as the General Catalogue of 10,300 Multiple and Double Stars.
