Description

Decided to shoot this nebula after seeing it in some of the widefield panels for Project Patchwork. Though I think IC1318/γ Cyg can be used to describe most of the nebulosity around the star Sadr, stellarium has it directly over the bright nebula in this image. Also glad I framed up the cool looking nebula on the right. Stars are kinda shit but overall I'm loving the colors on this palette. Captured on September 20th, 21st, and 30th, 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

* AutomaticBackgroundExtraction

* [EZ Decon/EZ Denoise](https://darkarchon.internet-box.ch:8443/) (Ha only)

* EZ Soft Stretch

**Combining Channels:**

* PixelMath to combine monochrome channels into color image using CrazyPanda's formula:

> R= iif(Sii > .1, Sii, (Ha*.7))

> G= iif(Ha > 0.7, 1-(1-Oiii)*(1-(Ha-0.3)), Oiii *(Ha+0.7)

> B= iif(Oiii > .1, Oiii, (Ha*.3)+(Oiii*.2))

**Nonlinear:**

* LRGBCombination with Ha for lum

* Several [Curve](https://i.imgur.com/A0Ce5rh.jpg)Transformations to adjust lightness, hues, saturation, contrast, etc.

* Invert > SCNR > invert to tone back magentas

* ColorSaturation

* EZ Star Reduction

* LocalHistogramEqualization

* ACDNR

* More Curves

* Resample to 60%

* Annotation
