I am not OK with the artifact on bright stars of the slight deconvolution applied. I will try again.

Pre-processing done in Pixinsight :
- overscan area offset correction
- bias correction
- flat correction
- hot pixel correction
- debayer
- registration
- stack
Processing done in Pixinsight :
- backgroung color neutralisation
- color calibration using galaxy
- residual sky background substraction
- color saturation boost
- green neutral
- deconvolution
- non linear image creation
Final image :
- jpeg calibration done in Mac Photo
