OK, a few processing offroad trips on this one and a few potholes but back on track now.
This is the image I intended to show and didn't do so well on:

I knew the data was there but the processing and the monitors calibration were badly off. Thanks for the tips and suggestions.
Adobe Lightroom and PixInsight plus a slight tweak in Photoshop still.
PI did the best job of aligning and stacking these images compared to CCDstack which failed. CCDstack doesn't come across as one shot colour friendly.
