What you desperately need is the to-be-announced successor to the Nikon P900 - according to the rumor mills, its lens alone will take you to 3,000mm equivalent! Think what you'll be able to do if you factor in 2.5x digital zoom - 7,500mm equivalent! You'll finally get that elusive shot of the man in the moon!
Seriously though, to get that kind of detail from the moon, using a camera that you can easily carry one-handed... crazy times!
