That's looking great Gideon! Just a small question; did you use noise reduction? Seems like the background is just a little blurred to me.

Yes, guess I went a bit too much? I can see what you mean like here:

I had to reduce plenty of stars, these areas in RGB are always challenging.
This is actually the second edit I tried.

Yes, I do prefer the one without indeed. It shows a bit more detail overall. Bit of extra stretching and some saturation added and I think you'd have a similar result, with more detail.

Although I have it uploaded in AB, still haven't published yet in social, so might have another go...
Learnt some new tricks as well these past few days (although on a different target/ higher FL, but should help).
