Thanks Colin and Rom - I appreciate the guidance while I get the hang of things.
Did another reprocess in PI, adding a couple more steps early in the piece to improve star white balance:
- Background Neutralisation (defaults)
- Colour Calibration (defaults with a "starfield" region of interest)
Has significantly reduced the colour tweaking effort later in the workflow.
Updated crop attached.

Still working through a few reference materials.
But throwing the racquet at a few images along the way with a cut-down workflow initially certainly aids the absorption and retention of info.
Thanks again.
