Sinus Iridum from a patch of excellent seeing Tuesday Morning. At 235 km diameter from promontory to promontory, the sinus (bay or recess) looks like a perfect bite out of the Jura mountains in which it intrudes.
The poetic relationship between Sinus Iridum - the Bay of Rainbows - and its parent body of "water", Mare Imbrium - the Sea of Rain - is hard to miss. The bay is a remnant crater flooded when an impactor crashed into what is now Mare Imbrium and sent a flood of lava into the crater burying the southern portion.

Thanks, Steve. Yes lunar imaging is one of those things you either love or don't. Lots of shots of the same crater at different phases searching for the "perfect" pic!
