This classic star atlas is ideal for both beginning astronomers and more experienced observers worldwide. The clear, full-color maps show stars, clusters and galaxies visible with binoculars or a small telescope. The atlas also features constellation boundaries and the Milky Way, and lists objects that are interesting to observe. This new edition features a clearer map of the Moon's surface, showing craters and features; a second Moon map, mirror reversed for users of telescopes with star diagonals; enhanced index charts showing the constellations more clearly; and a new data table listing stars hosting planetary systems. It is now spiral bound, making it ideal for use at the telescope.

This is the ideal resource for beginners and experienced stargazers in the United States and Canada, and has been updated to include new and practical information covering events occurring in North America's night sky throughout 2021.
