6 by 9-inches, 368 pages, 156 illustrations and 21 tables.In the last few years webcam astrophotography has exploded onto the astronomy scene. It has rapidly evolved from short exposure six-bit black-and-white imagery into long-exposure full-color 16-bit per channel imagery of such qualitythat it rivals conventional means of astrophotography. Indeed, webcams have become the method of choice for planetary imaging. The message of this book is that you too can participate in this revolution without spending very much money. You do not need to invest $10,000 in a CCD camera, telescope and software. A basic webcam costs about the same as a "so-so"eyepiece. Software to control the camera and process the images that will get you going is free. If you have the telescope (practically any telescope that will track) and a computer you are ready. Since you see your results instantly the learning curve is much shorter. Regardless of how you apply a webcam to astrophotography, you will derive a number of benefits. Working with them has been accurately described as interesting, challenging, and fulfilling. Webcams are capable of producing beautiful astrophotos that create a lasting record of your astronomical experience. The book will guide you into this fascinating topic and allow you tobecome a participant in this latest wave of astrophotography progress. About the Author: Nearly 50 years ago Robert Reeves began his astrophotography adventure with his parent's Voightlander 120-format camera. His first exposure from his south- Texasgarage roof was the brightest object in the sky, which turned out to be Jupiter. Unlike today's readily available books and accessories that make astrophotography more user friendly, back then the budding enthusiast was left to his or her own devices. Robert was not deterred and found a lifelong avocation of imaging the universe with his camera. His images have been published in the leading astronomy magazines and books and in 2000 he wrote the highly acclaimed book Wide-Field Astrophotography followed in 2005 by Introduction to Digital Astrophotography detailing the opportunities presented by consumer digital cameras.

6 by 9-inches, 448 pages,.This book is a 400+ page comprehensive, nuts-and-bolts introduction to digital astro-imaging written by Robert Reeves, an accomplished author and film imager with nearly 50 years of experience who has enthusiastically made the transition to digital imaging. Robert describes how the family digital camera you probably already own can be used to take spectacular pictures of the night sky. This is especially true if you have purchased a digital camera within the past several years - even some entry level point-and-shoot digital cameras take pictures of the Moon and planets that rival or exceed the best film images. If you already own a digital camera, telescope, and computer you probably only require a cameraadapter and image processing software some of which is free to begin your night sky imaging adventures and unlike film you see your results almost instantly!

About the Front Cover Photography: To assemble this spectacular composite of M42, the Great Nebula in Orion, exposures of differing ISOs were taken and combined by Rick Krejci to show both the bright inner core of the nebula and its fainter outer portions. Three five-minute exposures at ISO 100, 6 five-minute exposures at ISO 200, 7 fiveminute exposures at ISO 400, and 3 five-minute exposures at ISO 800, all taken with a Canon 10D through a Takahashi CN212 at f /3.9, were combined to create the final image.
