Description

Image of M104, The Sombrero Galaxy, was capered in LRGB + NIR (Sloan-i filter). NIR was used to "beat pollution". Image has SNR of 7.5.
Two panels are LRGB-NIR (Panel B) and LRGB-NIR annotation (Panel A)

Processing:
WBPP was used to combine all Lum and NIR frames. It is named LNIR.
R, G, B and LNIR were cropped.
GraExpert applied for R, G, B, and LNIR
RGB were combined.
DBE for RGB
Color calibration for RGB.
Blur and Noise XT for RGB and LNIR.  
Star XT on RGB. 
Manual stretching in HT for RGB-stars (moderate stretch), RGB and LNIR
LRGB-NIR was created by using LRGB-combined (RGB + LNIR).
Noise XT, stretch again.
Star XT. Stars are discarded. 
Mask with Lum, which is enhanced with Curves.
LHE, Kernel radius 40 and 150, power 0.3
MMT sharp (0.02-0.04 setting)
Curve for saturation, hue and brightness adjustment for galaxy.
Curve for star saturation of RGB stars.
Added RGB stars to the Galaxy (Panel B).
Annotation (Panel A)
Done.
