A couple more from the 10th, this is Archimedes (left), a stack of 1500/3500 frames, 9 point alignment in registax, and Rima Hyginus (right).

There are some joins still visible, registax had a lot of trouble with this one for some reason...

Nice shots Anthony, the rilles are great. Looks like the seeing let you down though.

Yeah, the seeing was below average for these, maybe 4/10 or something.

cheers, Bird

Very nice!
Do they know what causes the rilles?

Umm, I think it's lava that shrank and cracked when it cooled...
