Notes
Sketched these two craters which lie to the north of Mare Crisium. Hahn, which has a central mountain, was completely dark within. Beorsus was half lit from its pointy side, which faces west.

Was quite taken with the shapes in the Mare Angus to the north of the pair. From this photo you can see one shpae that looks like an erect penis and another, not visible in the photo that resembles an elongate Homer Simpson.

Hahn was named for an 18th century German astronomer Comte Friedrich von Hahn, who discovered the central star in the ring nebula in 1800 using an 18" reflector.

Crater Berosus is named for a 3rd century Babylonian preist and astronomer. He is said to have discovered the sundial and written a history o Babylonia.
