Christian Legrand et Patrick Chevalley have released VMA v4.0. http://ap-i.net/avl/en/start http://ap-i.net/avl/en/download It is simply astounding lunar observing freeware - something that will blow your socks off. The Pro version is 400Mb but integrates all the major lunar maps (geologic, Clementine false ratio, Apollo and Lunar Orbiter, best amateur images) into one interface. I am preparing a DVD which will be made available for lending to local club members. - Kurt
