I used some earlier data taken with the same scope and camera except at native F7. I took
some extra shots this week at F11.2 and combined them in CCDstack which did it effortlessly.

TEC180FL, FLI ML8300, Baader LRGB 260 150 130 120.

Greg,
This is a rally nice image. I think you nailed the colors. When some of us fellas up North try to do this, it is low on the horizon and due to atmospheric extinction, the colors come out red. I have applied extinction factors as gain adjustments to the RGB signal. It helps,but I think your image shows that it is much better if you don't have to deal with this.

Great job.
