About this image

We have had so many clear nights recently I've had no time to process and post any images. For example, I've obtained Venus images almost every evening for the last month.

This was a very low low waning Moon taken in a single shot with a DSLR and 100ED scope. At this phase the Mare Nectaris (below the middle of the terminator) appears to be a multi-ring basin. I don't know if it is the official selenogical opinion that it is such, though.

Mare Nectaris is indeed the central, lava-filled part of the multi-ringed Nectaris Basin. In fact, when the lighting conditions are just right it’s possible to see what might be indications of a third inner ring buried beneath the mare lavas.

It seems to me that the conditions are just right in the image above.  Careful examination of the enlarged image leads me to that belief.  However, I may just be deluded.
