The image was taken during the end of the first quarter of the Moon. The interest here is to bring out the relief of the craters in the region of the terminator (part between shadow and light during the first and last quarter of the Moon). This region is on the left side of the Moon. It features a lot of craters left down. This region includes the well-known Tycho crater. Higher, still to the left, the most famous crater of the Moon, Copernicus, is also highlighted. See the annotation in the following link:
