Data from the Messier Catalog, a catalog compiled by the French astronomer Charles Messier between 1758 and 1782, contains the brightest depth-of-field objects. These include open clusters, globular clusters, nebulae, and galaxies, and by mistake a double star was included (Messier 40).

Extracted, key entries from the NGC catalog. The NGC (New General Catalog) is the most common catalog of depth-of-field objects among amateur astronomers. The NGC catalog was compiled in the 1880s by J. L. E. Dreyer, largely based on earlier observations by William Herschel.
