EDITORIAL INFORMATION When it arrived on the scene in 1981, the original Sky Atlas 2000.0 by Will Tirion was the most comprehensive set of star charts tailored for the coordinate equinox now in universal use. Carefully planned and executed with the active observer in mind, the atlas contained some 43.000 stars to visual magnitude 8.0 and about 2,500 deep-sky objects. Without departing from that work's philosophy and chart arrangement, this second edition brings with it many significant enhancements. By going to magnitude 8.5 instead of 8.0 we have nearly doubled the number of plotted stars, ensuring that star patterns will be easier to recognize at the telescope or in binoculars. The number of deep-sky objects is increased as well, but more modestly, to about 2,700. Like its predecessor, this second edition comes in three fromats. The full-size, wirebound, Deluxe Version - with a generous scale of 8.2 milimeters per degree - uses color encoding to help distinguish deep-sky objects and the Milky Way from ordinary stars. The stars for this new edition are its most sweeping enhancement. They are taken from the Hipparcos and Tycho Catalogues, the fruit of nearly four years of all-sky scans by the European Space Agency's Hipparcos satellite. (Extracted from the Introduction).
