The the sky the night of the 19th was quite obscured with marine haze and it was dewy and cold, and I was tired... I tried one double but was discouraged of seeing many of the B stars, so went on to a very rewarding session on the moon.
BU 677: Upped the magnification, to make sure no trick; checked the CDSA index to make sure what I was seeing -- 2 delta mag but very wide faint stars. There's another one I notice with averted vision and then can hold with direct, which is another of the set. [AB was the first, AC the second 11.2, 15.5"]
20H 47M 10.72S +34° 22' 26.8" P.A. 120 SEP 8.1 MAG 4.94,10.03 SP K3III
I used 310x and binoviewers, as the seeing was good 8/10. I started out with crater John Herschel, then South -- the two observing buddies with adjacent craters, both with rough and rubbly floors, but Herschel being the larger. I was able to just make out Sharp Rille and a quavering line below the Louville hills. Gruithuisen Domes were interesting, being among the largest of the type and steep-sided. Harbinger Mountains and Prinz Rilles next, and I could see a few more smaller of these besides the main five. Crater Caroline Herschel was a night sight, a multi-terraced, sharp round crater. I checked crater Kriger to see if it had its rabbit ear shadows, but they were stumpy -- I must be a day late to catch them. The Marius Rille made a great impression (no pun intended), long and sinuous with a long rounded hook. I checked carefully for Suess Rille but could not see it.
