Not sure what to think about this. I've not invested a lot of time in reprocessing but am happy enough with the result. I've attached the original (processed in StarTools) and the new image reprocessed (in PixInsight). HaRGB, around5 hours in total, with my usual setup - ED80, HEQ5, ASI1600MM-Pro - taken a couple of months back under some dark skies. PixInsight trial about to expire so getting in what I can!
