After a few days and several attempts I am leaving it here until I can get more data, NEED more SII data if nothing else. After colour calibration everything in the background is just filled with red dots, everything besides the Pillars region (quite nice SNR) is red dots
So I've gone and 2x2 drizzled and then cropped some of the central region out and made a 4096x4096 pixel region to play with. It has the FOV of a 14" F/3.8 and KAF-16803... just without the aperture or signal of such an instrument

Oh and significantly lighter!
Although I don't mind the magenta/red stars, some are still a bit distracting so I do need to rework those when I've got some more data.
