A large wall chart showing the stars of the night sky in three superbly clear and detailed maps of the Northern and Southern hemispheres and the equatorial region.
As well as showing all stars visible with the naked eye, the charts show more than 200 deep sky objects including galaxies, nebulae and all the Messier objects. The maps are accompanied by tables of interesting objects, such as double stars, variable stars, star clusters and nebulae and lists of suggested targets to help plan observing sessions.
