Except for a few guiding hiccoughs I had a productive night last night. This is 25x180s subs for each of Ha, OIII and SII. While processing it I noticed there is still plenty of noise in OIII and SII so maybe I should treat it as a work in progress. Still not sure about the colours!
Looks great! How did you go about processing the image? I’m itching to go to the narrowband side and keen to see if most process in PI or what other options folks use.
Ben, all processing (including calibration, registration and stacking) was done in PixInsight. I'm still learning as it's so complex and there is more than one way to do most things but there are plenty of resources on the Internet to help.
