After several weeks of treatment and draft for this target, here is my last treatment.
I first used the "BatchPreProcessing" script in Pixinsight as well as many other scripts (SNRMax, AutoColor, AdvStarmask, PSFImage, Arcsinstretch, ...). This greatly facilitated my task.

The image is not perfect but I wanted to get an image with a consequent detail in structures and stars. The brutes, especially the Luminance is extraordinary.

In conclusion, this target apparently simple and of great complexity of treatment.

Thank you to the people who helped, supported and advised me for this treatment.

Wishing you a clear sky.
