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 Aucune description trouvée dans une bibliothèque |

A few of the good points follow;
Spiral bound so easy to lay open.
Constelations are drawn out and labeled, and are very recognizable.
large numbers of non-star objects are placed on the atlas. These objects are classed in about four categories, red for galaxies, yeppow for open clusters, green for nebulas and so on.
Often this coloring becomes useless or hidden when outside under red light. However, the author and his helpers insured that these objects would indeed stillb e there because the objects are outlined by a narrow black band. This is just one insight into the practicality of the book.
Another good feature is the limiting magnitude. It is just a little fainter, but not much than naked eye, so is a good match for both naked eye finding obkects and for finder positioning.
There are many charts and indexes occur both in the front and back of the atlas.
The book is also made of durable material. ( )
