Hitchhiker's Guide to Rukl Chart 30

Encke (David North <d _at_ timocharis.com>)

Encke is one of the most hexagonal craters on the moon.

Maestlin (...Akkana)

Long shadows in the ghost crater Maestlin, near Encke, at UT 6/13/2000 at 0430, though they were rapidly shortening even then.

Kepler (...Akkana)

Kepler has a terrace in its wall, very prominent when it's near the terminator.

Rima Milichius (David North <d _at_ timocharis.com>)

A difficult fight, but can be seen in a C8, even though Rukl calls it "not observable in small telescopes".
