This book is very well written and easy to understand for amateurs like myself. Written by an amateur for amateurs, the language is very down to earth. I'm not very technical so for me this book was very welcome. If there is anything i could miss, it's dealing with windows7 issues, but one can get that info on the net, if needed. So all in all, I like this book very much, and recommend it to any amateur interested in digital astrophotography!
