Marth, a concentric crater

Marth, a concentric crater.
When you look at this picture, I'm sure you'll be attracted to Ramsden and his set of Rimae.
It really is a remarkable formation, attracts the look at first sight, there is no denying its beauty, even more so in a photo like this with low angle of illumination.
I, however, who seek more subtle things, who am also in love with the concentric lunar craters (see article at: http://www.astrobin.com/276753/?image_list_page=2&nc=&nce=) could not fail to notice Marth.
Unfortunately due to the low angle of illumination it was only possible to capture part of the double wall that makes up this remarkable concentric. With the sun at a higher angle it would probably be possible to photograph it with the same prominence of details that I photographed Hesiodus A (http://www.astrobin.com/full/291643/0/?nc=user) on exactly the same day.
Marth is a small concentric lunar crater located in the northwestern part of Palus Epidemiarum. To the northwest is the Dunthorne Crater, and to the southwest is Ramsden.
It was numbered at 105 in David Trang's dissertation, 2014 (p.146-149) which is the most complete catalog for 2014, containing114 of these craters. In the 1978 list, my great friend Chuck Wood received the number 27, which was done in much more precarious conditions than the current one due to the great advance of amateur astrophotography as well as the data sent by the lunar orbiter probe (LROC).
Marth is unusual for having a double edge, with a smaller inner crater concentric to the outer edge. The smaller crater is located near the center of the larger ledge, giving the feature a target appearance.

Moved to 'Imaging - Lunar' :smile:

Great looking image as always. And a very interesting crater - makes you wonder about its origin.
