Has recently been updated to version 2.1. An excellent resource for
moon observers, to complement Rukl. It is nearly 200pages long with
excellent photos mostly taken by th author, at 80Mb you will need a
fast internet connection (or a friend) to get a copy.

Available free from http://alanchuhk.sev84.001at.com/

Well worth it and well done Alan for all his hard work.

Enjoy.
