Many thanks guys.
Mark - I'm hoping I can get my act together and add RGB before the Rosette is gone for year. Plenty happy with this effort in the meantime.
Paul - thanks - I wouldn't be so addicted to astrophotography if people like you would stop posting new masterpieces all the time...!
Werner - cheers mate - you've got no apologising to do with the great work you keep putting up! Struggling with exposure time and temperature noise on this very object was one thing that got me thinking about CCDs.
Thanks Martin! - I won't have to bore you to death at work now you've seen this one....
Thanks Pete - I see you've succumbed to 8300 fever already..!
