Indeed a nice shot, Marko :) On Astrobin you noted two different exposure time series, one with 180" subs and the other at 20". How does your processing workflow look like? Are you combining these subs with different exposure times while stacking or later on with post processing?

You managed to get a nice balance between taming the bright core and pronouncing the outer regions. There's a lot of faint stuff visible. Do you have dark skies at your location in Slovenia?

Best regards, Dietmar.

Many thanks, Dietmar.
I used two different exposures for the core so that it wouldn't be too burnt in the final photo.
In AstroPixelProcessor, I combined the photos in multi-shot mode, imported the image into StarTools, where I used the usual workflow.
Import Fits, AutoDev, Crop, Wipe, FilmDev, Bin 70%, HDR, Contrast, SVDecon, Sharpening, Colour, Shrink Stars, SuperStr (dim small stars), Track/NRand final FilmDev push up some Skyglow......
My sky quality is Bortle 4.
I apologize for the late reply.

CS, Marko
