Jase I have tried a few of your suggestions and pushed the curves a bit harder removed more majenta and tweaked the dust lane.
Don't know if I've been successful though! As you say it's a matter of pushing to see what's there without ruining the background. A bit of trial and error to eventually get to a point you are reasonably happy with the result.
I will probably do better now if I go back to the original stack and start over and try to get everything coming together.
David and I really appreciate your willingness to share your tips to help us improve our images. Thanks again
I have included a before and after
