Rick,
There is loads of cirrus in that area! At first, I thought I had dodgy flats, but, careful use of MMT has brought out incredible detail. Furthermore, I have lowered the contrast with HT and CT. That has reduced the overwhelming cirrus. When all the data is captured, I will emphasise the cirrus.
If you saw how noisy the original image was compared to the smooth result I am showing here, your jaw would drop. I am absolutey floored by how incredibly powerful MMT is! I spent a considerable amount of time learning its ins and outs by working on various previews. Best. Tool. Ever. That, and the HDRMT tool to bring out the dust lanes in the galaxy, where it was previously just a smear. Unreal.
I'll post the original stack when I get home tonight.
