Not really familiar with this one Peter, but certainly looks like a really nice field. You've got the 3 types of nebs popping alright that Paul mentioned. Might even be worth playing with Colour Saturation on the blues in PI to see if it pops any more. Your rendition is nice and subtle though, so I'm probably only going to create trouble.
Now feeling peer pressure to check this one out sometime - suspect optimal imaging approach would require Crownie however?
