Product Description
Review
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)
Product Description
Digital electronic imaging devices allow the wonders of the universe to be seen in detail never before possible from an amateur astronomer’s backyard. This book clearly examines how to create the best astronomical images possible with a digital camera. It reveals the astonishing images that can be obtained with simple equipment, the right software, and knowledge of how to use it. Completely jargon-free, the book describes how to extract results from the raw-and-dirty original imagery and then transform them into high-quality pictures suitable for framing, posting online, or sharing with friends and colleagues.

Format:Paperback
A rather thin volume (140pp), with most illustrations in B&W, however it does give a decent overview of the subject. Whilst published in 2007, the material is at least 2 years older (and some 10 years older). The author seems to have taken on board the 'rule of popular science books' that every equation halves sales - as a result there are no real equations and very little 'hard' detail - in the chapter on Dark Frames, for example, we learn that the 'random noise' is 'mostly thermally induced' and that '(the noise) 'fades'(sic) by a factor for 2 for every 5 degrees C cooler' - plainly we are being left to make up our own formula here :-). Whilst it is mentioned (almost in passing) that Darks and Flats have to be created at the same temperature and exposure times as the images to be processed, the author then goes off on a pointless discussion of 'Master Darks' (and later, Master Flats) as if these had any validity beyond the current nights imaging session. One major annoyance is the Index, which is essentially useless. For example, 'noise' is not indexed at all (nor is anything 'thermal' or 'random'), whilst meaningless 'out of context' words such as 'gradient' (10 references) and 'mode' (6 refs) get 'pride of place'. Interestingly, 'moon' has 11 references and 'DSLR' 12 ! Talking of DSLR's, there seems to be no mention of 'RAW' mode, and, indeed, the author seems to take a rather cavalier approach to data preservation (or not) as he processes the image by skipping from one software package to another - under Image Handling you are recommended as a 'final issue' to store your images in FITS format, although we have to wait until the last page of the Appendix to learn how to do so (in that FITS 'plug ins' are available for Photoshop). All in all, a decent overview of the subject, although at a rather 'higher level' than I was hoping for.

Excellent Practical Source of Information
2 July 2007
Format:Paperback
I have been a serious photographer for several years, and an intermediate astronomer for the last couple years. I have recently decided to try and marry these two interests together in the form of astrophotography. This book has been an outstanding source of practical, usable information that has made the transition to using a telescope in conjunction with my cameras much easier and more enjoyable. I especially benefited from Privett's section on Image Reduction; I found several mistakes in my technique that I was not even aware I was making. Privett has a very readable writing style, and he also uses a subtle sense of humor to make the reading enjoyable, and not just a dry technical treatise. I also own one of Privett's other books, The Deep-Sky Observer's Year, and these two books go together very well for planning what to shoot, and knowing how to shoot. I heartily recommend this book for anyone who wants practical advice on how to improve their digital astrophotography results.

Not worth the money
31 Mar 2007
Format:Paperback|Amazon Verified Purchase
To start, this book is not 244 pages, it is 142 pages including indexes and appendices. I had hoped for a tutorial that would take you through the process of taking, processing and displaying astro photos. Given the advertised 244 pages (and the relatively high price) it seemed a reasonable expectation. It's not that there is something wrong, it's just that it's not anything special and for the price it should be. Bottom line, it's not worth the money

The Zen approach to astro imaging? Save your money!
19 Feb 2009
Format:Paperback|Amazon Verified Purchase
This is a 142 page booklet, the essence of which could have fit easily in less than 100 pages. The writing style is wordy and abstract. The depth of coverage would suffice to enlighten only the totally uninitiated, and then only barely. Save you money.
