A bright full moon tonight so I set up my 1000/100mm refractor. I thought the atmosphere was fairly bubbly so I didnt try any high powered views.
I just took one video around Mare Crisium and Proclus (L12), a crater with a bright ray system, like a protractor.
It was only when I compared the final image against a moon atlas that I noticed right at the eastern limb, the multi-lobular appearance of Mare Marginalis, a lava-filled mare that can only be seen if the moon’s wobble (libration) permits.
This is actually number 100 in Charles Wood’s Lunar 100 because it is rarely visible.
This particular tilt also means that L70, the Humboldt basin is visible tonight.
I think that brings me up to about 27/100 or so but it’s nice to tick off number 100.
