I've never seen a better perspective shot with 2 planetary bodies. shots with earth in the background are cool, but since earth is just a dot you really cant get any appreciation of the relative size and distance of the 2 planets.
I dont think there's a better shot to be had in the entire solar system. and only saturn, with its rings, can look so detailed in the background.
thats a Life magazine, picture of the year nominee. Bravo!
