This is the largest and most comprehensive atlas of the universe ever created for amateur astronomers. It is the first major observing guide for amateurs since Burnham's Celestial Handbook. With finder charts of large-scale and unprecedented detail, in both normal and mirror-image views, and an extensive list of 14,000 objects, it provides a detailed observing guide for almost any practical amateur astronomer, up to the most advanced. The atlas has about 270 double star images and sketches, and 590 or so deep-sky images and sketches. Spanning some 3,000 pages, this is a project that is possible only on CD-ROM. The CD-R pages are extensively indexed and referenced for quick location of objects, areas, classes of objects etc. The accompanying book gives an introduction to the Atlas, showcases the maps (thus buyers can see what they are getting without running the CD-R), describes the CD-R content and organization, and includes various appendices. This is much more than just a catalog of objects.
