NGC 1365 high gain

Set up last night at midnight as the clouds were clearing just to do some backlash measurements. So not great but anyway... I was waiting for Orion to clear the trees as the seeing was really poor, lots of dew, and figured I'd take Alex's advice and give high gain a bash. The optimal exposure calc in Nina said 15 secs at 350 gain (unity is 139), normally I would expect below a second at that gain for NGC1365.

46 x 30s
-10C, gain 350.
ASI1600MC. EON 85.
Uncalibrated.

Best single frame for reference, jus a stretch
