Astro-imaging is a bit of a dark art. I have been attempting to make a reasonable attempt at it for years and you pick up a few tips along the way. This book essentially puts all the tips into one handy reference. Each section is written by a successful imager who basically guides the reader through a set process that they have used to good effect. You will learn about the programs as you go along and hopefully be able to repeat the process without forgetting it. I have learned a great deal from it and my images have improved as a result. I actually think this is one of the best books I have read on this subject and I have read a few over the years. If you want to improve your images then this book should be on your book shelf.
