Pointed at the big search light in the sky last night. Rather fun from the usual deepsky.

14" Meade ACF on its forks and the ASI533MC at native focal length around 3800mm.
Looks a little dark. But feel like I'm over exposing while live stacking in Sharpcap. I'm in the first 30% of the histogram. Before throwing in the the VIP Barlow for a mosaic. Any tips to improve my result?

Thank you for that. Very useful and informative. Some tweaking then.

As Mike says, one of the challenges is trying not to blow out or saturate the bright spots. Exposure looks pretty good, actually. The 533 camera captures a linear image and a linear image will always look dark. Apply some gamma to bring up the background. A DSLR does this automatically, your eye acts in a similar way, bringing up the darker parts of the image.
