The 20 charts that make up The Cambridge Star Atlas 2000.0 show the sky in multiple colors: Stars are black, the Milky Way is blue, star clusters are yellow, nebulae are green, and galaxies are red. Wil Tirion also created the more detailed The Cambridge Star Atlas 2000.0, which adds about 900 deep-sky objects to maps that plot stars to magnitude 6.5. A keyed series of six finder charts shows readers how the atlas maps relate to the current night sky. Magnified inset charts show the Pleiades (M45) and the region around Orion’s Sword. The maps include constellation boundaries but no constellation figures. The Bright Star Atlas divides the sky into four polar and six equatorial zones. It also includes about 600 double stars, variable stars, and deep-sky objects. Aimed at users of the smallest backyard telescopes, the Bright Star Atlas shows stars to magnitude 6.5. Another favorite atlas in the beginner category is the Bright Star Atlas by Wil Tirion.
