The Cambridge Star Atlas covers the entire skies, both northern and southern latitudes, in an attractive format that is suitable for beginners and experienced astronomical observers. It contains maps of the Moon, a series of seasonal sky maps and a small eight-page atlas showing all of the Messier objects, which also serves as an index to the main Atlas charts; a detailed atlas of the whole sky, arranged in 20 overlapping full-color charts. The charts shows stars down to magnitude 6.5, together with about 900 non-stellar objects, such as clusters and galaxies, which can be seen with biboculars or a small telescope. Information about this objects can be found in the tables that accompany the charts.
