Took another stab at andromeda. Really cloudy and humid night so almost gave up and went inside. In a clear spell decided to shoot short exposures at max iso again. This is 90 x 20s exposures @ ISO 25600. I attempted to stack in mosaic mode but there were distinct lines between regions so I just cropped the best one...

Steven - much better detail in the core than on your previous attempt. Beautiful shot. You really hit on a good combination with short exposures and super high iso. I might have to look into a new camera one of these days. rich
