Ptolemaeus et al.......

Thanks lads for the encouragement....

Donal, thanks for the heads up on the "Imaging Source" newsletter..... That was a nice surprise!!!! I wasn't expecting that!!!!

Good stuff Steve!!

What is the feature about half way up on the left of the image. It appears to be a track of some kind coming from the crater to the NE of it.

Those are the Catena Davy craters which some believe may be a chain of volcanic craters. Alternatively, it is believed to be due to a single body that broke apart prior to impact due to tidal effects, similar to Comet Shoemaker-Levy 9, which split into numerous fragments in 1992 and struck Jupiter in 1994. The largest craters in Catena Davy are 3 kilometers across.

Thanks Steve. I was thinking they looked like they were created by fragments of the same body that impacted the surface. Not sure i'd go for the volcanic theory..........but i can see why some do.

Wow Steve what a great image well done mate pin sharp. And great detail.
