It’s one of the most recognisable objects in the night sky and one of the hardest to process due to the massive differences in brightness between the inner core and outer dusty regions. I managed to pull it out using local histogram equalization in PixInsight, although I was unable to avoid it causing dark halos on the brighter stars, even when using a star mask. Not bad for 6 subs though, will need to try and add to it.
