Product Description
Objects in the Sky brings together all the list and all the objects of mag 10 or less in a form that's convenient for use at-the-scope.
Pocket-size astronomy field guide features all known deep-sky objects to Magnitutde 10 for telescope and binocular observation. All types of galaxies, clusters and nebulae were painstakingly culled from every available catalog, organized and cross-referenced for ease of use at the viewing site. Object-oriented maps include special symbols to aid in identifying objects, stars, double stars, and asterisms. Simple enough for the beginner. Detailed for the advanced.
The digest-sized, spiral bound Third Edition features 680 northern hemisphere deep-sky objects, all with Y2K or better hyparcos data. Those objects of mag 7 and brighter - ''city'' objects - are highlighted in the lists and in the 63 maps. Astronomical details are in ''expanded shorthand'' and set large for reading by flashlight. Newly included are 144 double/multiple stars and several brief constellation grouping stories which present the bigger picture. These stories have proven helpful teaching the sky to kids of all ages.
This multi-purpose guide is most convenient at the viewing site instead of carrying larger, bulkier books and computers, or as a companion to the larger sky atlases when planning a night's viewing. It's compact size makes it ideal for camping, hiking or in the car.

About the Author
Peter Birren is an award-winning graphic designer, self-employed since 1975. His interest in astronomy began as a young child when his father casually pointed out a bright, orange Mars drifting in the summer sky. Since then he has independently studied the heavens through extensive reading and observing. This interest expanded to the development of an invention which is presently being used by NASA on the X-38 Space Station Lifeboat. His viewing equipment includes an antique 6-inch reflector, updated and recoated, combined with a 12x50 tripod-mounted binocular, and adjustable telescope seat.
Peter is also a very active hang glider pilot, flying since 1977. He's president of a flying club, has almost 1000 flights with many hundreds of hours airtime logged, and has performed in numerous airshows across the country with the Manbirds Hang Gliding Team.
