What a night of observing! The wind was light and the sky was clear. The Moon was on day 18 of it's lunar cycle. It took over 1 hour of capturing and nearly 5 Gigabytes of data to capture this beautiful Moon, though it was only after I started that I realised this was going to take a lot longer than my previous mosaic on day 5 of the lunar phase! Overall I am very pleased with the performance of the ED80 and it's lack of any colour helps to preserve detail.

Mare Orientale is just visible in this image as the libration of the Moon is approaching a maximum in this direction on 7th December. Terminator details include Aristoteles, Eudoxus, Mare Serenitatis, the walls of Posidonius, Theophilus, Hommel and an unusal mountain on the southern limb which casts a deep shadow.
