Details:
Mare Fecundidatis and Mare Crisium were instrumentally visualized last March 2016. Ephemerids for March 12th observation was a 3.6 days lunation and 317 degrees colongitude.
From all craters in the field, sputtered with “small impacts”, easily seen on Mare Fecunditatis Crater Langrenus and Taruntius highlights whereas crater Lick observation, on Mare Crisium, was a rare opportunity due sun low elevation angle. A similar effect help to make apparent extra features such as Dorsa Geikie, and Dorsa Mawson in Mare Fecundidatis. Likewise, on Mare Crisium part of Dorsum Oppel, Dorsum Termier and Dorsa Harker are found. An additional band crossing Mare Crisium by its half is noticeable as a lengthy dark rim. Could not identify or find its name.
Messier craters, like others, looks to be in complete darkness. Its impact tails are barely discernable despite sun elevation, however. Picture 2 (taken with same optics some time ago) is another of so many examples of how Messier and Messier A crater looks under sub-solar conditions.
Same vintage Meade LX3 SCT. Same observation rotten conditions.
