Thanks to Frank for bringing to our notice Godfray's book on Astronomy, in the context of a solution to the minimum-twilight problem. I hadn't come across him, or it, before. A look through the contents index immediately put it into my must-have category, and as is often the case with old textbooks, a copy was availably locally for a few pounds. It's on its way.
