Processing steps:
1) Weighted Batch Pre-processing
2) Dynamic Background Extraction (DBE) for removing background gradient
3) Spectrophotometric Color Calibration (SPCC)
4) Generalized Hyperbolic Stretch (GHS)
5) Noise Exterminator (color and luminance noise reduction) and Blur Exterminator (deconvolution and sharpening) by RC Astro
6) Starless image created with StarXTerminator by RC Astro
7) Bill Blanshan's StarReductionMethod3_V2 pixel math applied for star reduction
