Description

Having imaged Crater Gassendi in some detail I swung out to a wider FOV. These are RGB images and were produced from single imaging runs on each colour channel of 4 to 8 minutes duration as I limited the file size to 8GB. Again the excellent seeing resulted in very good resolution and image clarity.

The smooth surfaces of Oceanus Procellarum at bottom left and Mare Humorum at upper right are punctured by beautiful small craters and contrast the mountainous and highly cratered region to the right in the image.

The mottled blue-green-grey colours of the "seas" are very evident and one can imagine the lava flowing in and around the higher ground, which is lighter in colour to form this region.

The larger round crater punctuating the Oceanus Procellarum at left is Herigonius with one of its children "E" to its right.

Most of the craters in this region were flooded by lava, with Mersenius the largest. Its lava flooded floor is quite pocked marked from impacts and there are several rilles formed as the lava shrank. The large tear shaped crater to its south (up) is Liebig (37kms) and to its left is a shallower tear shaped crater Liebig D. At the edge of the frame in deep shadow is Crater Cavendish (56kms).
