Maurice sent a note about his new lunar website and while looking through it I came across this informative view. It is one of his images that he rectified using LTVT. I like it because it provides a slightly unfamiliar perspective, helping us to notice things differently. First I really like that huge curved basin at top right - it's much bigger than most other nearside basins. And there must be a bright ray crater over the top left limb. Did you notice the small basin with a flat, dark floor just on the terminator downward and left from Crisium? From our normal Earth view Crisium looks round, but its really more like a pear. The distended eastern (bottom) side doesn't have the continuous, even if saw-toothy, mountainous edge. The patches of mare beyond Crisium's main massif boundary occur in areas where its outer rings are, but I never noticed before that most of it is on the eastern half of the basin. In fact, I guess Cleomedes is flooded with lava because it is in a moat between rings. Finally, why is the area from Petavius and Langrenus towards the terminator so smooth? It looks gray and flatish, whereas most other areas that distance from the terminator are rougher.
