Description: I added another couple of hours of data and also added in some Ha data. Total integration is 310 x 30s subs + 20 x 4m Ha subs. I also tried for the first time breaking my RGB into channels and performing the linear processing on each of them before combining. Adding in the Ha data is also something I have never tried to do, it really made the Red Ha pop which I personally like. A shout out to Trevor from AstroBackYard for encouraging me to process channels independently and also to add in Ha to my color images. Also a thanks to Christopher Gomez for the good YouTube tutorial on how to combine Ha with RGB data in PI. Comments welcome!
