This is my Best image so far, it's of the Fighting Dragons. It's a 2 panel mosaic and my main goal was to create a Hubble palette image from the Antlia Ha & OIII filter i recently bought to pair with my 533mc pro.

Linear Preprocessing
Stack with WBPP
Crop with DynamicCrop
Remove gradients using ABE
SCNR
Extract Ha and OIII
Use ChannelExtraction (RGB):
Create HOO Colour Image
Combine Ha and OIII into an RGB image using PixelMath
Linear Processing Before Stretching
Run BlurXTerminator
Run NoiseXTerminator
Run StarXTerminator
Stretch the Starless Image
Stretch the image with HistogramTransformation and STF
Enhance Colours and Contrast
RGB/K tab: Apply soft S-curve for contrast
Saturation tab: Increase saturation slightly
Red channel: Lift midtones to enhance Ha
Blue channel: Boost mids for OIII
Green channel: Slightly reduce
Add Stars Back
Slightly stretch stars-only image with HistogramTransformation
Thats my full process, I Developed it from a mix of places so i'm still no where near finding my full workflow, any advice is greatly appreciated!
Cheers,
Sunil
