Creating and Enhancing Digital Astro Images
Description
The book will, in jargon-free blow-by-blow terms, describe how to create the best astronomical images you can with the digital camera equipment at your disposal. It will explain the steps we go through to extract results from the raw-and-dirty original imagery, and then transform them into high quality pictures that you could hang on your wall.
The advent of CCDs, and more recently inexpensive webcams, has led to a much greater proportion of amateur astronomers becoming involved in digital imaging. The low price of the new Meade Deep Sky Imager - $299 (2005) - suggests that within a few years a simple digital camera will become a standard accessory for any telescope.
To summarise; this is a book that tells practical astronomers (and that includes some but not all professionals) what is needed to get from standing in the dark with a telescope and a camera, to showing your spouse, local society friends or even supervisor the astonishing images that can be obtained with simple equipment but the right software and knowledge of how to use it.

From the reviews: "This book is packed with sound practical advice about digital imaging. . The book is aimed at beginners and experts . . there is plenty of information in this book and it gives an excellent general overview of the subject." (Pete Lawrence, BBC Sky at Night, August, 2007) "This recent addition to Patrick Moore's Practical Astronomy series is chock-full of helpful tips for anyone considering attaching a camera to a telescope. . I highly recommend it for beginners or for advanced imagers who concentrate on one photographic discipline and need an introduction to the other ones." (Sean Walker, Sky & Telescope, November, 2007) "Privett has certainly packed a bundle of useful information into one hundred and fifty pages, with hardly an equation in sight! . His advice is both relevant and concise and clearly reflects years of practical experience . . There is a good index at the back as well as useful appendices on hardware and software, and a helpful list of acronyms and abbreviations . . I got a good feeling from this book - a nice blend of genuine enthusiasm and expert knowledge comes clearly across." (Gerard Mc Mahon, Astronomy and Space, December, 2007)More details
