Interesting features on a waning moon.

Fri Nov 18, 2016 1:49 pm

On the 16th November the cloud cleared sufficiently to observe the waning gibbous moon. The shadows gave some interest to some lunar features.

Note the crater Petavius at the top, totally in shadow apart from its rim and central peak. The peak reveals a small crater in its foothills.
The crater Rheita, the strange elongated companion Rheita E, and the roughly chiselled Rheita Valley are located in the middle of the image. At the bottom is the large shallow crater Janssen with the smaller overlapping craters. The Janssen Rille is clearly seen running south through it.

Another image I took on the same occasion shows the Mare Crisium.
