Description

This is first my image with FWHM<2. Nothing was changed, just happened. Probably, seeing was good after 1am. 
Processing of globular clusters is still "mystery" for me. I think key point is that how HDR Multiscale Transform will be executed. I applied it for Lightness and no Deringing. 

Processing:
RGB combine.
Dynamic Crop for RGB and Lum
Color calibration for RGB
DBE for RGB and Lum
Blur and Noise XT for RGB and Lum. Blur XT could give "worm-like structure", if image too bright. This could be seen on brighter version. 
Manual stretching in HT for RGB and Lum
LRGB is created.
Noise XT, stretch again.
Mask by Lum enhanced with Morphological Transformation.
HDR Multiscale Transform 
Curve for star saturation and brightness adjustment
Done.

I have two modification: original version and brighter version.
