About this image

I've already posted this image in the Moon discussion forum. I found it very interesting how Bailly at this illumination and libration created the powerful impression of a hump on the terminator. It looked, in this view, as if it was at the southern cusp of the Moon, but panning the view along showed it was well away from the cusp. The effect was plainly due to the distant wall of this vast plain catching the light, while all the surrounding terrain was shadowed.
