- iOptron CEM40
- ZWO ASI1600-MM Pro
- ZWO Sii/Ha/Oiii filters
Integration Time
- Ha: 263x180s (13.15 hours)

Processing
- Preprocessing using WBPP
- SubframeSelector > ImageIntegration > Drizzle Integration
- DynamicCrop + DBE on individual Ha/Oiii/Sii channels
- LinearFit all channels to Sii
- PixelMath to create color image with R=0.7*Sii+0.3*Ha / G=Oiii / B=0.9*Oiii+0.1*Ha
- BackgroundNeutralization + ColorCalibration on RGB image
- PixelMath to create L image with avg(Ha, Sii, Oiii)
- TGV + MMT for denoising on L image
- 2x ArcsinhStretch + HistogramTransformation on both RGB & L
- 2x LocalHistogramEqualization on L channel
- LRGBCombination to combine L + RGB images
- Curves for color balance, saturation, and contrast
- Star reduction using MorphologicalTransformation with a contours mask.
