Thanks for your comments Peter, Martin, and Dave.
Peter, here are the processes I used in Pixinsight:
- Dynamic crop
- DBE
- Deconvolution (Followed procedure from VisibleDark on YouTube)
- Stretch
- LocalHistEq applied twice at 64 & 256 with a stretched luminance mask at about 0.35ish amount.
- Starnet2
- Worked on stars a little (morphology, saturation, SCNR, invert+SCNR for magenta reduction)
- Next, I split the channels, combined B and G, stretched it to roughly match the red channel and renamed B. Next I combined 0.6*R+0.4*B for my green channel. I combined all these in LRGBcombination with R as my luminance.
- Worked on colour curves in the nebula. Bumped up the blue mid-tones overall, then used a yellow mask to work on the “orange” hydrogen, and a blue mask to work on the oxygen. Also tweaked other curves: RGB, luminance, saturation,…
- ColorCalibration. Then tweaked colours again a little.
- Combined stars with nebula
- NoiseXterminator at default settings
- Sharpened: Unsharp on a luminance clone, MLT on another luminance clone, then created a new luminance: 15% Unsharp + 15% MLT + 70% lum clone. Then used this as L in LRGB combination.
That’s pretty much it I think. I’d be very curious to receive an analysis on the processes I’m using, their order, and processes I am not using which could have benefited this image.
