Image of Lex publicated in Image Processing Challenges. Main notes: CBR and DEB to correct background, Convolution to reduce noise pattern, sharpen with MMT. Date: May 2012.
StarAlignment with L as reference.
DynamicBackgroundExtraction to L (Notice that I am working with out STF)
HistogramEqualization to a Clone.
CanonBandingReduction Scriptto see results in the clone.
Delete the clone and CanonBandingReduction to image.
Open B channel and DynamicBackgroundExtraction.
B channel after DynamicBackgroundExtraction and the noise I was talking about.
Open G channel and DynamicBackgroundExtraction.
G channel after DynamicBackgroundExtraction.
RGB Combination (ChannelCombination).
Whit AberrationInspector Script generate a the preview for BackgroundNeutralization.
Increasing protection of RangeMask with MorphologicalTransformation.
Convolution before and after protecting stars with RangeMask.

SCNR to Green.
Noise reduction. MultiscaleMedianTransform protecting the galaxy with RangeMask.
HDRMT protecting galaxy core with RangeMask.
New HDRMT protecting with new Range Mask.
Luminance Mask applying HistogramTransformation and ATrousWaveletTransform on inversed Luminance.
