Tycho, Schiller, Hainzl:

Mare Humorum:

In this image you can find the Rimae Mersennius, Rima Hippalus (very weak),

Gassendi, Sirsalis

The biggest crater in this image is the floor fractured crater Gassendi, to the lower right of the image you can see the Sirsalis Rille and a “mouse” ;-)

Kepler, Marius, Reiner

Kepler is the bright rayed crater in the upper half of the image in the lower portion of the image you can see the Marius Hills, a collection of volcanic domes, to the right of the hills is Reiner Gamma a mysterious patch of bright material that might be caused by a local magnetic anomaly.

Herschel, Pythagoras, Babbage

Mare Marginis

Mare Marginis is the collection of dark mare material visible near the edge of the moon in the upper left of the image. The very bright crater at the right lower corner is Proclus, it has a very conspicuos ray pattern which indiciates an oblique impact.

Aristarchus, Rümker

Aristarchus is the brightest part of the moon, it is overexposed in the image below. Right next to Aristarchus is the Schröter Valley, a sinuous Rille. In the lower left of the image you can see Mons Rümker sitting right on the terminator. It is the biggest volcanic dome on the moon.
