Stacked Dumbbell

I took this image on the August 7. This is cropped image from a stack of 5 x 15-second integrations using the DS 2,3+ and the f/4 Newt. I turned the gain down to around 3 and the stacked image is a huge improvement over my earlier image (a couple of posts ago) where high gain resulted in prominent stacking artifacts.

The stacking produced some slightly misshapen stars, but overall, it's a much better pic.
