With 60 hours of imaging over, I have gathered all the data I set out to gather for the IC1396 Elephant Trunk Nebula image in Narrowband Hubble Palette. This image involved a 4-panel mosaic with 10 exposures per filter, per panel. All exposures were 30 minutes long, captured with Sulphur-II, Hydrogen-Alpha and Oxygen-III 3nm filters. The following is the end result: The above end result required a refined narrowband image post-processing workflow in PixInsight. This made use of the exceptional work by Rick S. from the PixInsight forums, who made the ColorMask script. This script is able to produce a mask image from a range of colour hue values, thereby selecting out specific colours for post-processing. I personally think it is worth mentioning use of this script in the tutorial about touching up colour in narrowband images, so it will happen soon enough.

Beautiful work Kayron. Can you tell me, do you use the Gibraltar Astronomical Society's optimum exposure calculator to decide upon exposure times? I tried it during one of my recent sessions and I thought I got pretty good results. But I see your times are pretty long. So either you have exceptional skies or you use some other method to decide this.
