To the North-East of Mare Serenitatis lies Atlas, a 53-mile circular crater which is about 3000m deep. It features a central mountain which is clearly visible here. Atlas forms a remarkable couple with its neighbour, 42-mile crater Hercules which in turn features a prominent, smaller crater Hercules G in its floor - not seen here as Hercules' floor is still mostly covered in darkness. The smaller crater towards the North is Keldysh (20 mile diameter).

Doubling the effective focal length to f/20 yields some further magnification, but did not really reveal more detail, other than better defined shadows on the crater floor of Hercules:
