Just nit picking its LRGB imaging. Luminance got added to RGB imaging several years ago.
So LRGB imaging not RGB imaging which is very rare as it lacks the detail LRGB gets.
Adding Ha to LRGB adds some extra depth and detail and if often very pleasing. Adding some O111 also can help get some nice blues going.
Sulphur is pretty much useless unless doing a full narrowband image.
I personally mostly do LRGB imaging and often HaLRGB even occasionally HaRGB (not often).
Greg.
