The first photo is my attempt and the second one is my end goal I got some data sets off of telescope live to practise processing I did a pretty good one for the rosette nebula but I'm struggling on this one (the cat paw nebula) and I can't seem to find a YouTube video that is good what I specifically need so if anyone knows a YouTube video that can help me or any tips that would be great. I use siril or dss for stacking I use graxpert and adobe photoshop and the files are halpha, OIII and SII
