| The new edition of the world-famous Uranometria 2000.0 star atlas is the most comprehensive printed stellar/deep sky atlas and data resource available to the amateur astronomer. The star charts are available in two separate volumes – Volume 1, which covers the northern celestial hemisphere to a declination of - 6°, and Volume 2, which covers the southern celestial hemisphere to a declination of + 6°. Both volumes are needed for complete coverage of the sky for observers in the northern hemisphere. The third volume is this 545-page Deep Sky Field Guide. It provides detailed basic catalog data, in easy-to-use numerically ordered chart-by-chart tabular form, for the 30,000+ nonstellar objects plotted on the 220 Uranometria 2000.0 charts. The information is useful visually with telescopes of any aperture, as well as for CCD imagers and astrophotographers. The data includes the precise coordinates, magnitude, and size for each object. It also include data specific to the various types of objects. Notes are provided for 23,358 objects and include a description of each object and the direction to and the magnitude of nearby stars, using either the Hubble GSC (Guide Star Catalog) or Tycho catalogs. Such information can pinpoint an object’s location, which is particularly useful for very low surface brightness objects that might be difficult to locate visually. The notes also provide common names, as well as alternate catalog names. The notes also give the direction and distance to nearly 1,000 nearby nonstellar objects (usually galaxies) that are not plotted on the charts (as these “challenge objects" are usually quite faint and below the charts limiting threshold). This Field Guide has more accurate catalog data for three times the number of deep sky objects than was shown in the preceding edition of Uranometria. This new edition of Uranometria 2000.0 is clearly a star atlas and field guide that every telescope user, whatever their telescope aperture, will want to own. The Information Provided in This Field Guide for Each Star Chart in Volume 1 and 2 . . . - Individual galaxies: You get the exact right ascension and declination of each plotted galaxy; its name; visual magnitude; dimensions; surface brightness; type and DDO luminosity class; and position angles. Nearby stars and nonstellar objects are noted.
- Galaxy clusters: You get the right ascension and declination of the cluster; its name; the magnitude of its ten brightest galaxies; the number of galaxies in the cluster; the diameter of the cluster; and notes on the cluster.
- Open clusters and star clouds: You get the right ascension and declination of the cluster or cloud; its name; its diameter; its magnitude; the magnitude of the brightest star; the number of stars in the cluster; its type; and notes.
- Globular clusters: You get the right ascension and declination of the cluster; its name; its diameter; its total visual magnitude; the magnitude of the brightest star; the horizontal branch visual magnitude; its concentration class; and notes.
- Bright nebulas: You get the right ascension and declination of the nebula; its name; its dimensions; its brightness; its color; and notes.
- Dark nebulas: You get the right ascension and declination of the nebula; its name; its dimensions, major and minor axis; its opacity; and notes from E. E. Barnard’s Atlas and Catalog.
- Planetary nebulas: You get the right ascension and declination of the nebula; its name; its diameter; its photographic magnitude; its visual magnitude; the magnitude of its central star; any alternate name; and notes.
