This was a quick peek at the moon taken right before covering my gear after a long night of imaging. The setting sun is setting over Sinus Iridum near the moon’s northern limb and you can glimpse Mare Orientale just peeking over the southwestern limb. Mare Orientale is one of my favorite lunar features even though it is often hidden just out of view on the moon’s backside, though you can often see the impact basin’s ring mountains in profile against the black sky. This is also the location of the famous “bull’s eye” picture taken by Lunar Orbiter 4 in 1967.
