This is a revision of my last picture.
I've had 3 more panels, to remove the reflexion of Sirius, and to had more field to the top of the picture (I missed one panel last time).
There are 15 panels.

I've changed the projection of the mosaic in APP to limit distortions on the edges of the picture.

I'm now satisfied with this result, considering my sky quality ;-)

Edit : I've made a version B, with more contrast and saturation, but I prefer the version A, more natural ;-)
