I did set the gain higher as it gave me more contrast. The movies look better than the monitor:  lots of little cells about a hundred pixels across slowly breathing.  Breathe in, breathe out.

Great to see all these Scorpion stings!

Howard - You've done a nice job keep some bright tonality in  

Aristarchus. Overall, the image seems noisy to me considering a stack  

of 900 frames. I would think a lunar capture at this focal ratio  

should be possible with low gain and would expect the individual  

frames to have very low noise prior to stacking.
