With more than 275,000 copies in print since its original publication in 1983, Nightwatch has become a standard reference guide for stargazers throughout the Northern Hemisphere. The enlarged third edition of the book was issued in 1998, but this new fourth printing has been re-issued this year with even more revisions and the latest astronomical statistics and information. Comprehensive field guide for amateur stargazers, featuring 20 specially created full-colour deep-sky star charts and 256 full colour photographs. Special full-colour sections cover the stars, constellations, nebulae, planets, the sun and moon, eclipses, comets and meteors. Ultra-simplified jargon-free text offers substantial information for the novice and intermediate astronomer on equipment and photography. New edition features spiral binding for lay-flat use next to your telescope
