I don’t know if nature is that strange, but there is something similar in lunar imaging. Once someone cracks the code and acquires a remarkable image of a feature, other imagers soon do it too. This is not meant at all to disparage this or any other image, but it is simply awesome that very subtle features such as the rille on the floor of the Alpine Valley that used to be nearly impossible to image are becoming more familiar. Mike’s excellent image with his 10″ dobsonian telescope not only shows the rille and it sinuosity but also the crater pits along the rille and the cross-structure near its middle. The nature of the structure is not clear, even after looking at the high res Lunar Orbiter V [http://www.lpod.org/coppermine/displayimage.php?album=32&pos=2 shot]. From Mike’s image the curved dark shadow suggests a low fault cuts across the Valley.
