CCD : Sbig STL-11000M
Filters : Baader L,R,G,B
Exposure time : Luminance 540 min binned 1x1  Red,Green, Blue 120 min each binned 2x2

PIXINSIGHT 1.7 PROCESSING :

ImageCalibration
Defectmap
StarAlignment
Luminance image integration with LinearFit Clipping :
-dynamic crop,
-DBE
-Deconvolution with DynamicPSF
-MultiscaleMedianTransform MMT noise reduction image
-MMT Sharpening
-Histogram stretched
-Star size reduction : Morphological transformation
-HST adjust the final blackpoint

RGB processing
- Dynamic crop on each R,G,B,
- DBE on each R,G,B
- R, G , B combine channels
- Color calibration
- MMT noise reduction
- Histogram stretch
-Color Boost : luminance mask +curvestransformation on saturation
-SCNR green with maximum neutral setting

LRGB combine
-Dynamic registration of RGB to Lum
-LinearFit Lum  to RGB extracted Lum
-Lum combine to RGB , transfer function Saturation default
-HDRMultiscaleTransform
HDRMT 8 layers   Median Transform on, Lightness mask + Luminance checked , inverted starmask on luminance
-final Histogram Stretch
-ACDNR noise reduction
