Book Description Sky Atlas 2000.0 in its second edition offers nearly 90，000 stars， with all positions derived from the Hipparcos database， the most accurate survey ever undertaken. In this Desk Version， the 29 charts show stars and deep-sky objects in black on a white background. The map area is 460 x 330 mm (18 by 13 inches). The charts are printed on heavy paper， and for ease of use they are unbound and boxed. In this format the Atlas will be indispensable as an aid to telescope users who prefer to plan their observing on the desktop.
