The Lunar "X"

South is up in this image. Following the current IAU definition, east is to the left.

The "X" is the pattern to the east (left) of the terminator just above the center. The deeply shadowed craters below and slightly to the right of the "X" are Werner (top) and Aliacensis (bottom). To the west (right) of the "X", is Blanchinus with la Caille (mostly hidden in shadow)  just above the "X". The left side of the "X" is formed by the western rim of Purbach.
