This is the southern end of the Oceanus Procellarum, south of which is a rugged area which divides it from the Mare Humorum. Visible is
the Sirsalis Rille (Rima Sirsalis) which is one of the longest rilles on the Moon being over 300 Km long
and extends to the south beyond the area of this picture. (The full length can be seen on this picture.) It is a most unusual rille in that it cuts
across highland terrain rather than skirting the edges of a mare like most rilles do.
LPOD has a stunning image of it together with
Dr Wood's usual authoratative description.
The scale markers are approximately 100 Km north and east.
The picture was taken in green light with a DMK camera attached to my LX200 on 27th March 2010 at 23:31 UT when the Moon was 12.3 days old.
