Norton's Star Atlas is a set of 16 celestial charts, first published in 1910 and currently in its 20th edition under the editorship of Ian Ridpath. The Star Atlas covers the entire northern and southern sky, with accompanying reference information for amateur astronomers. The charts used in the first 17 editions of the Atlas were drawn by a British schoolmaster, Arthur Philip Norton (1876–1955), after whom the Atlas was named. Norton intended his star atlas to be used in conjunction with the highly popular observing handbooks written by the British astronomers William Henry Smyth and Thomas William Webb, and consequently most of the objects featured in those guidebooks were marked on the charts. The Atlas also found favour among professional astronomers, earning it the reputation of the most widely used and best-known celestial atlas of its day.
