Back in April, Graham e-mailed a number of BAA folk, but which did not include David A., the following: “The astronomy content is at a very introductory level. One aim is to get existing photographers out there to be as amazed as I have been in recent years by what can be done with ordinary digital cameras as long as you get away from the light polluted towns. The book should also be useful to those who are already astronomers but have not yet tried photography (Part 3 is about practical techniques and every photo in the book has full details of how it was taken).
Another aim is to get youngsters interested in something technical. The book is intended to be suitable for school pupils.
Hopefully this puts the book more in perspective.
