Hi David,
Really nice image
I am sure as you experiment with PI and data processing and refer to the materials that Rick generously gave us, more and more of this esoteric knowledge will "make sense" again
I started working on the same nebula and aiming to create its narrowband interpretation, but only got 30% of data at this stage. Hopefully the skies will remain cooperative for the next week or so.
Looking forward to seeing a new version with added G&B data, that should add a wider range of colouration to the image.
