Korte beschrijving: The DSFG provides, by Uranometria 2000.0 chart number, basic "observable" catalogue information for some 14,000 nonstellar objects. In this way, it attempts to make dry catalogue listings more useful to the amateur observer in the field. The selection of deep-sky objects in Uranometria 2000.0 was based primarily on The Revised New General Catalogue of Nonstellar Astronomical Objects (RNGC) of Sulentic and Tifft. Additional objects not in the RNGC were added from Hirshfeld and Sinnott's Sky Catalogue 2000.0, Volume 2. This was particularly important for all types of nebulae and for open clusters, among which are large numbers of readily visible objects not included in the NGC. Sky Catalogue 2000.0 (and thus Uranometria 2000.0 ) also lists hundreds of mostly dwarf galaxies that are quite faint but which have low radial velocities ("redshifts"). These are considered to be relatively near us in space and thus of interest.
