Looks like this gem is out of print
This book is really a gem. While it covers all aspects of astrophotography, including equipment, film, etc..., its real strength and main focus is determining exposure. Most other books I've examined are weak on this point. They give fairly vague rules of thumb and tell you to bracket exposures to make sure you get a good result. This book doesn't do that.

Gordon has developed an extremely precise system for determining what exposure time is required for a given lens, a given aperture (f-stop), and a given astronomical object. I've used the system several times and it has always produced a perfect exposure the FIRST time, with no bracketing required (at first, I did bracket -- being a suspicious type, but the suggested exposure was always the best of the bracketed group, so I stopped).
