Very nice Mike - top shot as always!
Nice to scan around for the fuzzies.
Buuut, for my taste at least, it's an teensy bit blue and the colour noise up close is a weensy bit too much as well. It's hard to judge on my crappy work LCD monitor though (only 6 bit I think) - it acts like an astro image defect exaggerator

How long were your subs? I'll bet you had to do some serious stretching to reveal the cirrus?
Cheers,
