Although I love the palette in this image the stars need work. Somehow despite not touching my optical train I need to readjust my coma corrector spacing. This has led to the oblong stars in the corner, and is likely the reason for bloated stars overall. My focus was dead on, but my HFR when shooting was around 2.8, where my typical narrowband HFRs are in the 2.2-2.3 range. Captured on August 17th and 18th, 2019 from a bortle 7 zone.

* ImageIntegration
* DrizzleIntegration (2X, VarK 1.5)
* DynamicCrop
* DynamicBackgroundExtraction 2X
* Deconvolution per channel (With mask to only deconvolve the nebula. Used StarNet++ to create a star mask to add back in the original stars over the deconvolved ones. Star mask adjusted with binarize, convolution, and MorphologicalTransformation)
* TVG/MMT Noise Reduction (Jon Rista Method)
* HistogramTransformation (permanently apply Auto-STF Stretch)
* PixelMath to combine channels

> G=iif(Ha > 0.5, 1-(1-Oiii)*(1-(Ha-0.5)), Oiii *(Ha+0.5))
> B=iif(Oiii > .1, Oiii, (Ha\*.3)+(Oiii*.2))
* AutomaticBackgroundExtractor
* SCNR Green
* HDRMultiscaleTransform (Ha decon mask used as mask. HDRMT also applied to Ha stack)
* LRGBCombination (Ha stack used as luminance)
