Stunning indeed. Is that ERE in the background?

Yes, certainly stunning!

I am a bit curious about the apparent blue/red miss-alignment or cromatic aberration that I see when I look closer at the star field. Do you know what may cause it - the reducer? It does not spoil the overall impression and I am sorry for pixel peeping.......689355245_Skarmavbild2019-10-20kl_12_06_16.thumb.png.50cb4ae76bc805840912269c493a7227.png

You just need to stop pixel peeping, it's a full frame sensor with a reducer, the slightest focus drift or tilt will introduce this. I know it's your hobby, it was mine too some years ago 😉, I moved on.

Align channels in APP and less saturation makes the corners much better ...

Great, that was what I was thinking - aligning the channels could fix it. I even think it increased the overall impression of the sky. However, something may now have happened to the red in the galaxy, but maybe it is just my screen.
