Hi Pete,
That's looking much better!
Stars look neutral and no wacky oversaturated colours or registration issues, but it's still too contrasty imo.
Space isn't generally rendered pure black, so if you open up the blacks there's a lot more fine detail to be revealed from your data.
I took the liberty of briefly tweaking the image so you can se what I mean.
A more subtle approach will pay benefits at this stage of your journey.
I strongly recommend you get onto APP - (or Pixinsight if you're mathematically inclined.) These apps help enormously.
Cheers
Andy
