If you're planning to take your telescope outside on clear summer evenings, our new e-book Summer Deep Sky Observing Projects is perfect for your needs. The editors of Sky & Telescope have assembled 15 of the best articles from recent years about deep-sky observing. This convenient e-book gives you many dozens of telescopic targets, telling you how to find them and what you can expect to see. Galaxies, nebulae, star clusters -- they're all there, from finding the details in relatively bright objects such as the Whirlpool Galaxy (M51) and Pinwheel (M101) to tracking down distant galaxy clusters. All the objects described in the articles are visible in the evening during summer months. Happy hunting!
This book is only available as a downloadable PDF.
