Concise catalog of deep-sky objects: astrophysical information for 500 galaxies, clusters, and nebulae

Here is a unique and fascinating reference book for those who want to go beyond the Messier objects! Entries for each of more than 500 deep-sky objects provide far more than the usual astronomical data - they also give fascinating facts about each object. These include physical factors, astrophysical information, evolution, unusual features - the list is almost endless. The objects are all listed according to NGC number, i.e., in approximate order of location from west to east. This is convenient for observers because interesting objects that can be seen on a given night will usually occur within a few pages of each other in the book. The Messier objects are of course included, but are also listed separately in Messier number order. Astronomers can now get an insight into exactly what they are looking at, adding a new level of insight and enjoyment to deep-sky observing.
