Richard, much better than my best version of this galaxy. Detail is really
good.

I tried it last night, seeing was so bad the guide star was jumping from
8k to 13k ADU count one exposure to the next. It was bouncing all over
the fov even at 5 second exposures. By 10 it calmed down but left a
huge crab like image from its wanderings. Doubt I got anything usable.
Seeing did calm down after 2 a.m. but then I'd moved on to M51 which I
set up and went to bed. Not sure how that turned out.

Third character is a zero rather than a capital "Oh".
