Some Lunar closeups from last night. I had higher hopes for the seeing given the high pressure but I think being setting up on molten tarmac after a day in the Sun might have something to do with it too 🤣. Anyways, first up Copernicus crater with the day/night terminator cutting across, keeping most of the crater floor in darkness. Second is Rupes Recta, aka 'the straight wall', a linear fault, stretching over 110 km. Then last but not least, my favourite trio of craters, Ptolemaeus, Alphonsus and Arzachel, who decrease in both size and age from north to south making an interesting collective Asymmetry.
