I have (so far) 3 books published - there's something like 6 in the pipeline
Just sign in to Amazon, books, Greg Parker and you'll find the 3 books.
1) A textbook on semiconductor device physics. Not much photography there then
2) Making Beautiful Deep-Sky Images, published by Springer, a "how to" book for people wanting to take deep-sky images.
3) Star Vistas, with Noel Carboni, a pretty picture book of deep-sky images, also published by Springer.
