Clive and Jeanette, thanks for the advice and words of encouragement.
After looking at Eddie's magnificent image I think a few more hours are needed on this target to bring the dust and nebulosity out and keep it smooth. I'll hold off the repro's until more data is at hand.
It's pleasing to see time being invested on what is a remarkable bit of sky. I'll look forward to your image Clive.
Cheers
