Reihe: The Patrick Moore Practical Astronomy Series

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.
