I have been away from astronomy and astronomical sketching for many months and finally have been able to get out under a dark desert sky with my C-11. While others might have waited until the waning moon was further along, I had no problem beginning my astronomy catch up with lunar observing. I have sketched these two Imbrian age craters before but never under this illumination. What a nice pair and what nice contrast between the two. Hahn was already in shadow except a tiny bit of central peak showing while Berosus was still partly in sunlight with some very nice terracing evident. Magnification was 312X, seeing maybe a IV and transparency excellent. North is to the right and east is at the top. Berosus was named after a Chaldean astronomer that lived in the 3rd century BCE and he believed the moon was composed partly of fire and that it's rotation was synchronous with its orbit around the Earth. Not bad! Thanks for looking and I hope my fellow sketchers are all doing well!
