Description

This was shot very low in the sky with some of the subs coming in as low as 18 degrees. The highest was around 24-45 degrees. Being so low in the sky gradients were an issue. I used PI ABE and DBE to resolve as best I could.

24L, 19R, 23 G, and 15 B. All 10 minute subs, total of 13.5 hours. I created a super-luminance by adding the luminance data from the color subs to the luminance data itself. That increased SN significantly and helped allow more sharpening to be applied.

I plan to add some Ha and see what that does. Also some more Blue to help out. I sharpened the Luminance prior to creating the LRGB and it looks much more detailed that the final LRGB. I do shoot color bin 1 so I may just need a bit more?
