Just asking for some advice if their is a better tutorial on how to add NB to a RGB in pixinsight. The shapley 1 was one of my first hardest objects to try out.
I uses these to follow
http://www.lightvortexastronomy.com/tutorials.html.
Does this show the best way or are their other ways to combine a good looking natural object when doing a LRGB with HA and OIII?
