Final version
4 mosaic tiles from 2 different nights, each with c. 60x60s subs, making total of 255mins exposure time.
I've used Siril to:
- stack & preprocess each of the 4 images, using Dwarf3 dark, flat, bias files
- background extraction
- astrometric colour calibration
then stitched together, and followed with:
- star removal (starnet++)
- stretching the nebula and stars separately (Generalised Hyperbolic stretch)
recombined and then:
- sharpening / de-noising using Cosmic Clarity.
Any comments / recommendations on how to improve my process welcome.

Wow, tons better than the top part on it's own. Well done. You're coming on leaps and bounds.
Great mosaic Mark
Big improvement- well done
