I've captured some more photons and have polished this up a bit. I'm now calling this done. Apart from the fact that I have some interesting new targets, this region is fast setting early in the evening. I could tweak it more but have ru out of energy.
I've added Lum, R and G - roughly 4 hours of Lum and just under 3 hours of each of R, G and B. All images were unbinned.
On balance, I prefer this one - without the Ha. I always struggle to get the colour balance right. If I do succeed in eliminating the green from the background, the Ha area is very red. Without the Ha, I was able to keep the golden background.
Here is a link to the finished product - comments (cutting or helpful I don't mind) are welcome.
