Thanks Guys, yeh I have pulled this from IP into PS CS3 to finish off. I've applied a lot of tweak and every noise reduction going, but there are just so many settings in IP and PS for this sort of thing I don't know what's what.
I played around and could reduce the noise a fair bit, but at the cost of some detail. See attached. I'll give the process another go and leave out the 10min 800ISO run.
Oh well I'm learning stuff... just have that feeling I might be missing somethimnng fundamental
