Description

Morning of course being a relative term. The most prominent features/craters are Aristoteles the largest crater right of center and above center, Eudoxus below it and just starting to show are yhe outside rims of Aristillus and Autolycus, shown in the lower left region. The walls of Vallis Alpis are also just starting to show and I was hoping to capture the rille that runs down the middle it but I was 1-2 days too early. Some of the smallest craters measure about 1km in diameter. The seeing was above average and the moon was almost directly over me, giving me a fairly rare opportunity for lunar imaging. 

For more information and for those interested, I have copied information from Wikipedia.

It was officially named in 1935 after the ancient Greek philosopher Aristotle by the International Astronomical Union, using the classical form of his name.[1]To the immediate south of Aristoteles lies the slightly smaller crater Eudoxus, and these two form a distinctive pair for a telescope observer. An arc of mountains between these craters bends to the west before joining the walls. The smaller crater Mitchell is directly attached to the eastern rim of Aristoteles. To the west is the low, flooded feature Egede.Observers have noted the crater wall of Aristoteles is slightly distorted into a rounded hexagon shape. The inner walls are wide and finely terraced. The outer ramparts display a generally radial structure of hillocks through the extensive blanket of ejecta. The crater floor is uneven and covered in hilly ripples. Aristoteles does possess small central peaks but they are somewhat offset to the south. The interior floor appears to have been filled with a layer of material partially burying these projections.Aristoteles is a crater of Eratosthenian age.[2]
