A superb guidebook described in Bookwatch as 'the home astronomer's "bible"', Turn Left at Orion provides all the information beginning amateur astronomers need to observe the Moon, the planets and a whole host of celestial objects. Large format diagrams show these objects exactly as they appear in a small telescope and for each object there is information on the current state of our astronomical knowledge. Revised and updated, this new edition contains a chapter with ten new spreads describing spectacular deep sky objects visible from the southern hemisphere, and tips on observing the upcoming transits of Venus. It also discusses Dobsonian telescopes, with hints on using personal computers and the Internet as aids for planning an observing session. Also new to this edition are redrawn "Guidepost" figures at the beginning of each season chapter that allow readers to visualize a three-dimensional view of the sky's dome; redesigned seasonal object layouts that provide more space for the naked-eye charts; a new spread on double stars near Boötes has been added to Spring, replacing the "Shrinking Double" spread; and a unique "When and Where to Look" table has been added to the last page, among other new features. Unlike many guides to the night sky, this book is specifically written for observers using small telescopes. Clear and easy to use, this fascinating book will appeal to skywatchers of all ages and backgrounds. No previous knowledge of astronomy is needed.

" excellent book for small telescope users...As the resurgence in small telescopes continues, this book will be of use to all users of such instruments. Since many of the objects covered in Turn Left at Orion can be seen from light-polluted skies, this book is a valuable asset even if you live in a large urban area." Deep Sky

"...should be packaged with every first telescope. It's as nearly perfect as such a book can be." Sky & Telescope

"...for those intent on doing some serious observing with a small telescope, Turn Left at Orion has much to recommend it." Stardust

"I think the format is perfect for beginners but even more advanced observers may learn a thing or two. It’s like having one of the KAS’s many experts right next to you at your ‘scope! It is commonly available in bookstores and libraries (including the KAS library). Two thumbs up (both of mine)." - Robert Havira, Cloudy Nights Telescope Reviews
