Mare Fecunditatis & Sinus Iridum

Hi all,

Here are some late arrivals that I have finally got around to processing from last year...

Mare Fecunditatis -
...I love the contrast in this scene between the well lit highlands on the left and the dramatic low lighting on the mare on the right with its ghost craters, ridges and secondary cratering from Langrenus (in deep shadow). Notice the sunken crater Ibn Battuta near the center where the mare lavas must have come right up to the rim. The contrast between the two areas is like chalk and cheese, as if they are two different images stuck together (it's not, honest! ;o)

Sinus Iridum -
This is from the day before a previous image, coincidentally almost exactly 24 hours apart. In the animated GIF the images are aligned on Promontorium Laplace to show the apparent 'shearing' effect of libration where features that are in a line roughly with the two promontories Laplace and Heraclides are stationary, whereas features above the line appear to move up and to the right on the next day, and below it move down and to the left.
