The most comprehensive stellar/deep sky atlas and data resource we have seen, the three volumes of Uranometria 2000.0 are so much more than a "Second Edition," they can only be considered the fulfillment of that process to which the first edition was but prologue. Years in development, this massive achievement affords astronomers, astrophotographersand CCD imagers the finest roadmap to the heavens yet produced at such a modest price . More than 280,000 stars and over 30,000 deep sky non-stellar objects are located with a degree of accuracy heretofore unavailable in one resource. Encyclopedic in nature, with beautifully redrawn maps, a host of efficient navigation tools, and more accurate catalog data for three times the number of deep sky objects shown in the preceding work, Uranometria 2000.0 is clearly an atlas and guide every telescope user, whatever their aperture, will want to own.
