This is my third year capturing M42, the Orion Nebula but it's the first year that I was able to get lots of detailed dark nebula surrounding the main subject. This is a blended image of 30-sec subs and 300-sec subs from two different data sets. The core, 30-sec subs, are one-shot color narrowband with an Optolong L-Extreme filter. The rest is from the 300-sec subs using a Radian Ultra Triad filter.

The two capture dates are 2/8/2021 for the core and 10/30/2021 for the rest.

Astro Pixel Processor Workflow for each set; 30 and 300 Sec subs:
0) Defaults
1) Single Session Processing: Sorting frames: quality
2) Checked create 32-bit Masters
3) 1000 stars
4) Defaults
5) Defaults
6) Lights to stack 90%, integrate Average, filter Winsorized Rejection, LNC Degree. 2nd degree

PixInsight Workflow:
Dynamic crop
Split into separate RGB channels
EZ Denoise on each
Automatic background Extraction, one step on each
Combined with LRGB tool back into one image
conservative Masked Stretch, Background Neutralization, Color Calibration

StarXterminator to make Stars and Starless images
Make a separate Lum layer from new image for later
Curves Transformation on Starless for saturation and contrast using color masks
Rangemask and Unsharp Mask on Starless to enhance brighter structures
Dark structure enhance script on Starless
Convolution on Stars image to smooth out the stars slightly
Curves Transformation on Stars Image for saturation and contrast
Convolution the starless image twice to blur the image
Edit the Lum image: Curves Transformation, Local Histogram Transformation, Dark structure enhance
Overlay Lum image over the blurred image to restore structure and image sharpness. 
Cleaned up and color balanced using the Color mask scripts and Curves Transformation
Create final version using PixelMath stars+Starless
Save Image as 16 bit TIFF for LightRoom

Lightroom:
Slight Exposure increase
Increase Whites slightly
White Balance adjustment
Additional Color Balance via Tone Curve
Luminescence adjustment via HSL
