I captured the Rosette Nebula from my backyard which has a SQM of 18.23 earlier this year. I recently purchased the NoiseXTerminator and StarXterminator products for PixInsight and for the first time I used them in my narrowband processing workflow. Here are the details :
Center Coordinates :
RA 6 31 55
DEC 4 56 58
Date : Feb 14 2022
SHO: 300s exposures 120gain 20 offset
Linear Processing
- WBPP
- STF
- Perform Linear Fit with Ha as reference; monitoring the HT graph for each image
- Dynamic Background Extraction for each filter
- NoiseXTerminator for each filter
- Create color masks for Red, Green, Cyan, Magenta
- StarXTerminator for each filter; split workflow for star and starless
- PixelMath combination for RGB:SHO mapping
Non-Linear Processing
- Application of color masks
- Histogram Transformation
- Curves Transformation
- SCNR
- Curves Transformation
Stars
- Histogram Transformation
- Curves Transformation (saturation, little lum adjustments)
Combine star and starless images with Photoshop Blend Pixel Math
- Dark Structures Enhance
- Color Saturation (little increase)
Pixel Math Formula for SHO
P.expression = "Sii*1+Ha*0+Oiii*0+Sii*0+Sii*0";
P.expression1 = "Sii*0+Ha*1+Oiii*0+Sii*0+Sii*0";
P.expression2 = "Sii*0+Ha*0+Oiii*1+Sii*0+Sii*0";
