Hitchhiker's Guide to Rukl Chart III

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

With the terminator cut just at the far edge of Neper and Jansky just out of view, Neper had a wonderfully defined central peak that seems to be edge to us (it's hard to imagine it's as deep as it appears wide) and an interior crater with a bright rim that could barely be seen past the shadow of its wall. But the truly remarkable aspect of Neper is the terracing of the inside wall -- if you want to hunt "edge on" craters, this is a prime specimen. Even in crappy seeing at 30x (and again at 100x with patience) three strata could be made out. It gives the illusion of being on the surface of the moon and looking at the far wall at sunset...

Mare Marginis, Neper, and Goddard (Randy Muller <71172.1234 _at_ compuserve.com>)

Both Mare Marginis and Mare Smythii were easily visible. I could barely make out what I believe were Neper and Goddard. Neper was located on the south edge of Mare Marginis and had light colored mountains in the middle of it. Goddard was a dark oval at the north edge of the Mare.

I could see all of Mare Smythii, including light lunar highland material at far edge of it at the limb.
