[The last time I photographed this nebula was in 2018](
https://www.reddit.com/r/astrophotography/comments/a8erew/ngc_7380_the_wizard_nebula/). I'd consider this an improvement. I fiddled around with some new false color combinations on this so any constructive criticism is appreciated. Also made a [time lapse of my telescope photographing this](
https://www.youtube.com/watch?v=xLU4TH0KEVo) (the clouds didn't affect things too much). Captured on August 9th 16th, and 26th, 2020 from a Bortle 6 zone.

**PixInsight Processing:**
* BatchPreProcessing
* SubframeSelector
* StarAlignment
* [Blink](
https://youtu.be/sJeuWZNWImE?t=40)
* ImageIntegration
* DrizzleIntegration (2x, VarK=1.5)
**Linear:**
* DynamicCrop
* DynamicBackgroundExtraction
* Deconvolution (Ha only)
* [EZ Denoise](
https://darkarchon.internet-box.ch:8443/) (Ha only)
* STF applied via HistogramTransformation to bring each channel nonlinear
**Combining Channels:**
* PixelMath to make classic SHO to RGB image
* Green completely nuked using SCNR
* Pixelmath to make RGB image using ForaxX's palette
> R= (Oiii^~Oiii)*Sii + ~(Oiii^~Oiii)*Ha
> G= ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii
> B= Oiii
* Pixelmath to blend classic and ForaxX SHO images 50:50
**Nonlinear:**
* LRGBCombination using stretched Ha as luminance
* shitloads of [curve](
https://i.imgur.com/c9jUDPw.jpg)transformations to adjust lightness, saturation, contract, hues, etc (some with luminance and yellow color masks)
* HistogramTransformation (lower black point)
* ACDNR
* LocalHistogramTransformation
* EZ Star Reduction
* DarkStructureEnhance
* More Curves
* MMT noise reduction
* Resample to 85%
* Annotation
