Thanks Steve. I suspect this will be a work-in-progress across multiple years which is an entirely new concept to me! But, I think it's heading in the right direction.

Thanks John. 30 redos - that's commitment and a chunk of time!! What are you working on? I got to redo #7 (I think) and had two separate versions of it; an LRGB, and, an LLRGB which is what I used for the shared image. The additional L was blended at only 30% and was good to highlight some extra detail in the arms. For background extraction, I'm slowly becoming a fan of DBE as it gives more control but can take much longer to get a good result. I also use GraXpert with good results but it does seem to add noise (which is easily cleaned up with NX).
