Perfect for experienced stargazers and beginners alike, Sky & Telescope's Pocket Sky Atlas will have you exploring the heavens in no time! Sky & Telescope 's celestial atlases are the standard by which all other star atlases have been judged for a half century. Now we've raised the bar again with our Pocket Sky Atlas - Jumbo Edition . There has never been such a wonderfully detailed atlas so handy to take on trips and use at the telescope, thanks to its user-friendly size, convenient spiral-bound design, and easy-to-read labels. The charts show both constellation boundaries and stick figures to help you find your way. Features of this atlas: More than 30,000 stars individually sized according to their relative brightness - 1,500 deep-sky objects color-coded by type, including 675 galaxies oriented as they appear in the sky - This Jumbo Edition has 6 new close-up charts, for a total of 10, depicting high-interest star fields. - Labels even more legible in dim light Roger Sinnott is a senior contributing editor of Sky & Telescope magazine.
