I gathered the lights for this over the 20/21 May weekend. 60x240sec exposures at unity gain with lights and darks only using an Altair 294C at -10. My processing skills before starting this were and still are very limited, i owe a thank you to Ruzeen and his Youtube channel AstroFarsography for teaching me how to better use Gimp.

I stacked in DSS, then moved to Siril to remove green noise, do a photometric colour calibration and background extraction. Then moved to Gimp, and finished with the free AstroSharp software. I 'm pleased with this result and hoping that when i move on to Pixinsight that scripts will do a lot of the work !
