I also saw this celestial scene this evening when coming home. But my foreground was more prosaic than the Gran Madre church and the Vittorio Emanuele I bridge that crosses the Po river. My brain somehow focused more on the Moon and Jupiter and they seemed bigger than in Stefano's camera view - caused because eyes are about equivalent to a 50 mm lens field of view and his camera was set at 18 mm. My eye was also better able to accommodate the range of brightness, clearly seeing the mare patches. By concentrating on the Moon I suppose that my eye did not have to try to obtain a correct "exposure" for the entire, largely dark scene. My brain did something else that the camera couldn't - it responded with a sense of pleasure.
