Processed using Deep Sky Stacker. Stretched using curves in Photoshop (only a small amount required). Added a bit of contrast and adjusted colour balance a bit. Reduced noise using Google Nik Dfine2 (Google Nik is now free!!). Finally, had to remove the red colour caste from the background due to using the Ha filter with a colour DSLR, to do this I loaded the saved TIF file into Nebulosity 4 and used the Adjust Colour Background feature.
