Visibility III / V
Ptolemaeus photographed just over a day after my previous attempt. Visually, looking at the Moon at Merz, the weather seemed so more worthy that I got excited to bite the tower with a more powerful but whimsical C11 tube.
The craters that remained under the floor of Ptolemaeus were no longer distinguished, except for Ptolemaeus B, which is to the north of the younger crater of Ammonius. The smaller, fresher craters at the base of Ptolemaicus stood out well in this illumination.
At the bottom of the Alphonsus are a series of slats and apparently volcanic tiny craters along them that have scattered dark matter around them. Alphonsus also specializes in a shallow ridge that runs through the crater.
South of Alphonsus are two craters with steep central peaks, Alpetragius and Arzachel. There are rills on the bottom of the Arzachel.
To the west of Ptolemaeus is a clever chain of small craters, Catena Davy. Charles Wood, the father of the Lunar 100 list, considers it the result of a collision of a comet that shattered into pieces, which seems like a fairly natural explanation, especially since there are also craters in the chain in the edge mountains of Davy Crater.
