I'll chime in here as usual and say that, IMO, the best single reference for CCD imaging is the Handbook of Astronomical Image Processing by Berry and Burnell. This is a 600+ page tutorial on every aspect of CCD imaging. All other books that I have read aspire to reach this level of detail and clarity. However, if you are looking for a book that will guide you through the process of choosing a camera, learning specific software functionality and producing "pretty pictures" this is not it, this book is hardware and software non-specific.
