Hardback. Etat : Good. Part of the satisfaction of watching birds is being able to name what you see. Yet, open a field guide, and there are hundreds of species to choose from, some with different appearances for males, females, immature birds, and even seasonal variation. It can be overwhelming. Where to start? The good news is that most people already know more than they realize about birds, and this can greatly simplify the identification process. These twelve steps start with the basics - such as location, habitat, and season - and then build logically into a manageable framework that can help anyone to identify and appreciate birds. For those new to bird watching, the book will help them understand the fundamentals of observation and the identification process. For more experienced birders, it helps them step back from years in the field and refresh their thoughts on how to watch and identify birds. Written in a helpful, conversational style, and illustrated with more than 85 colour photographs, this book outlines a pathway to enable anyone to get into, or get more out of, the world of watching, identifying, and enjoying birds. …

Paperback. Etat : Good. Charge-Coupled Devices (CCDs) are the state-of-the-art detector in many areas of observational science. Astronomy, physics, chemistry, medical imaging, and remote sensing are just a few of the fields of study in which they play a crucial role. This handbook provides a concise and accessible reference on all practical aspects of using CCDs. Starting with the electronic workings of CCDs, this handbook discusses their basic characteristics and then gives methods and examples of how to determine these values. While the focus of the book is on the use of CCDs in professional observational astronomy, advanced amateur astronomers, and researchers in physics, chemistry, medical imaging, and remote sensing will also find it very valuable. Tables of useful and hard-to-find data, and key practical equations round off the book and ensure that it provides an ideal introduction to the practical use of CCDs for graduate students, and a handy reference for more experienced users.…
