This is one of a series of images I took on 2nd May intending to do a mosaic of the terminator, but the seeing was unsterady at tumes and I abandoned the plan.  However this particular image came out well enough, it is a stack of best 40% of 800 frames with an infrared pass filter.    To my eyes Eratosthenes in the middle of the image between the Montes Carpatus and Montes Appeninus always looks like a watch or clock face with the hands set at 2am.
