About Books 0943396735

Willmann-Bell, Inc. is privileged to bring to press the stunning "Next Edition" of the world-famous Uranometria 2000.0. 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.

Books 0943396735 Features

  • Finder Charts: 8 large-scale, full-page maps (4 per volume), in 6 hour increments, keyed to main charts
  • Declination band tabs match main chart tabs
  • Stellar Objects: Limiting magnitude 9.75, close-up maps 11.0 from Hipparcos / Tycho catalog
  • Limiting magnitude 5.5
  • 280,035 Stars
  • 6,300 Variable Stars
  • Stellar taper, smooth (not binned)
  • 30,0000+ Non-Stellar Objects
  • The non-stellar database is now three times larger more than 30,000 objects and each object in this catalog has been verified by direct inspection of the Digital Sky Survey, Survey, Atlas of Selected Regions of the Milky Way, or Atlas of of Galactic Nebulae.
  • 25,895 Galaxies
  • Includes all NGC galaxies and others with a magnitude greater than 15.0, or a major axis of 1.5 or larger. Drawn to scale as open ovals, for galaxies greater than 5'
  • Those with a major axis less than 5´ are binned into the following ranges: 5´ 2´, 2´ 1´, and less than 1´. (There is a loose correlation between size and magnitude.)
  • All galaxies, except those with equal major and minor axes, are oriented on the chart in the direction of the major axis as determined by direct inspection of the Digital Sky Survey.
  • 671 Galaxy Clusters
  • Clusters are drawn as dashed open circles. Diameters for Abell objects are from Abell's Revised Catalog. For clusters from the Abell Supplement Catalog, diameters are estimated based upon distance class.
  • 1,647 Open Clusters: Objects larger than 5´ are drawn to scale.
  • 170 Globular Clusters: Globular clusters larger than 5´ are drawn to scale. On the close-up maps they are to drawn to scale if their diameter is larger than 1.5´.
  • 377 Bright Nebulae: If larger than 10´, objects are drawn to scale, otherwise as solid-line square boxes in two sizes (10´ to 5´ and less than 5´.)
  • 367 Dark Nebulae Objects are drawn with a dashed outline if larger than 10´. When smaller than 10´ they are drawn as dashed-line square boxes in two sizes (10´ to 5´ and less than 5´.)
  • 1,144 Planetary Nebulae Objects are plotted as open circles with four protruding lines in 4 selected sizes: greater than 30´´, 30´´ to 10´´, 10´´ to 5´´ and less than 5´
