Rezensionen

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)
