"This classic, groundbreaking guide has been the go-to field guide for both beginning and experienced amateur astronomers for nearly 30 years. Setting a new standard for astronomy guides, this fourth edition will serve as the touchstone for the next generation of stargazers as well as longtime devotees. Technology and astronomical understanding are evolving at a breathtaking clip, and to reflect the latest information about observing techniques and equipment, this massively revised and expanded edition has been rebuilt from the ground up (an additional 48 pages brings the page count to 416). Illustrated throughout with all-new photographs and star charts, the fourth edition boasts a refreshed design and features five brand-new chapters, including three essential essays on binocular, telescope and Moon tours by renowned astronomy writer Ken Hewitt-White, as well as new content on naked-eye sky sights, LED lighting technology, WiFi-enabled telescopes and the latest advances in binoculars, telescopes and other astronomical gear. An indispensable reference for all levels of stargazers."-- Provided by publisher.
