Notes:
NGC7635 - Bubble Nebula in SHO. I took this image over multiple nights in October and November of 2021 with my ED127 at 952mm. This is all of the data I could grab for this year. I'll try to add more data next year and see if I can make it cleaner and sharper.

PixInsight Workflow:
Dynamic crop
EZ Denoise
No Dynamic Background Extraction; Too Much Nebulosity
Combined Ha, SII, and OIII into an RGB image
Red:
SII
Green:
(Ha*.8)+(SII*.2)
Blue:
O_III

Conservative Masked Stretch, Background Neutralization, Color Calibration, SCNR Green 50%
StarXterminator to make Stars and Starless images
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
Create final version using PixelMath stars+Starless
Save Image as 16 bit TIFF for LightRoom

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

Topaz DeNoise to remove some leftover noise from the final image
