This book is the clearest, most complete, and up-to-date pocket guide to the heavens. Although compiled primarily for amateur astronomers, its utility for celestial navigation is obvious. Its features include: brief introductory tours of the nighttime sky; monthly sky maps for both northern and southern hemispheres; 52 detailed atlas charts of the entire sky; special timetables showing when the brightest stars, clusters, galaxies, and planets are visible; over 230 photographs (132 in color) of the most interesting objects in the sky.
