Book Description
With over 100,000 copies sold since first publication, this is one of the most popular astronomy books of all time. It is a unique guidebook to the night sky, providing all the information you need to observe a whole host of celestial objects. With a new spiral binding, this edition is even easier to use outdoors at the telescope and is the ideal beginner's book. Keeping its distinct one-object-per-spread format, this edition is also designed for Dobsonian telescopes, as well as for smaller reflectors and refractors, and covers Southern hemisphere objects in more detail. Large-format eyepiece views, positioned side-by-side, show objects exactly as they are seen through a telescope, and with improved directions, updated tables of astronomical information and an expanded night-by-night Moon section, it has never been easier to explore the night sky on your own. Many additional resources are available on the accompanying website, www.cambridge.org/turnleft.

Book Description
This book provides all the essential and best elements of Kidger's many courses taught worldwide on lens and optical design. It is written in a direct style that is compact, logical, and to the point--a tutorial in the best sense of the word. "I read my copy late last year and read it straight through, cover to cover. In fact, I read it no less than three times. Its elegant expositions, valuable insights, and up-front espousal of pre-design theory make it an outstanding work. It's in the same league with Conrady and Kingslake." Warren Smith.

Book Description
A valuable reference that fills a number of niches including that of a buyer's guide, technical desk reference and observer's field guide. It documents the past market and its evolution, right up to the present day. In addition to appealing to practical astronomers - and potentially saving them money - it is useful both as a historical reference and as a detailed review of the current market place for this bustling astronomical consumer product. What distinguishes this book from other publications on astronomy is the involvement of observers from all aspects of the astronomical community, and also the major manufacturers of equipment. It not only catalogs the technical aspects of the many modern eyepieces but also documents amateur observer reactions and impressions over the years, using many different eyepieces. Eyepieces are the most talked-about accessories and collectible items available to the amateur astronomer. No other item of equipment commands such vigorous debate, or has evolved into such a remarkable array of forms and functions. 'Choosing and Using Astronomical Eyepieces' provides a vast amount of reference material to point readers towards the best buys and the right eyepieces for different kinds of observing.

Book Description
The purpose of this book is to explain the basic principles of optics and image fomation particular to such lenses and optical systems. Much importance is placed on clear and detailed diagrams of contemporary equipment, and graphs of performance characteristics. The book begins with an explanation of visual perception, followed by sections on basic optics and image formation by representative systems; the design, the manufacture and testing of lenses andd optical systems; optical attachments, including filters and converters; the optics of a numbr of different types of camera; the projection of images; the anicllary and auxillary systems associated with image capture; and related optical and optp-electronic systems including fibre optics, LEDs and LCDs. The book is intended as a compact source of useful data, for anyone concerned with th visual communications industry, from secondary school pupils to professional camera users and euipment specialists. Sindey F Ray is Priniciple Lecturer in Photographic Sciences and Electronic Imaging at the University of Westminster. His other book for Focal Press, Applied photographic Optics has been acclaimed as the definitive work on the subject. he is also the co-author of The Manual of Photography.

Book Description
If you asked people to post a status update on their relationship with food, most would say "It's Complicated." We aspire to eat healthfully but find ourselves making hasty food choices driven by stress and convenience. Or we treat ourselves to a decadent dessert but feel so guilty we don't even enjoy it. The truth is we can't make good food decisions if we don't deeply examine our relationship with food. In The Food Therapist, Shira Lenchewski offers readers an ongoing one-on-one food therapy session, revealing the root causes of our emotional hang-ups around food and providing the necessary tools to overcome them. This practical and judgment-free guide helps readers hone the skills needed to put their get-healthy intentions into daily action, such as planning ahead wisely, tuning into their fullness cues, and harnessing willpower (even when life gets messy). Lenchewski also offers easy-to-follow, tasty recipes aimed at rebalancing our hormones and conquering our cravings without deprivation. The Food Therapist is a refreshingly modern resource that helps us finally un-complicate our relationship with food and our bodies. We can then focus our efforts on making thoughtful, healthy choices, day in and day out, which serve our ultimate goals, whatever they may be.

Book Description
For all but the simplest star-trail pictures, photographing the night sky involves machinery to track the stars, and the task becomes even more complicated when photographing very small or very faint objects that require high magnification or very long exposure times. Astrophotography for Amateurs presents equipment and techniques, features practical hints and tips from the experts, including coverage of traditional "wet" photography, CCD imaging, and computerized image enhancement. There are sections on photographing different classes of astronomical object from the moon to faint nebulae, as well as a detailed look at the equipment needed.

Book Description
A new vision is sweeping through ecological science: The dense web of dependencies that makes up an ecosystem has gained an added dimension-the dimension of time. Every field, forest, and park is full of living organisms adapted for relationships with creatures that are now extinct. In a vivid narrative, Connie Barlow shows how the idea of "missing partners" in nature evolved from isolated, curious examples into an idea that is transforming how ecologists understand the entire flora and fauna of the Americas. This fascinating book will enrich and deepen the experience of anyone who enjoys a stroll through the woods or even down an urban sidewalk. But this knowledge has a dark side too: Barlow's "ghost stories" teach us that the ripples of biodiversity loss around us now are just the leading edge of what may well become perilous cascades of extinction.
