This is a wonderful image Robin and far better than you realise it is. You just need a few processing techniques. I sent you a PM about this. Faster scopes, darker skies, higher QE cameras (the KAF8300 is right up there in the latest crop of Kodak sensors though) all help but in your case the biggest single gain will come from a few processing techniques.
The main thing in these faint fuzzies is advanced gradient handling. I have refined a technique from others that works really well.
Congrats on a super image. The data is there.
