Cat's Paw in Scorpio

NGC 6334 from the backyard in Perth. The scope is my ancient old Meade 10"f4.5 on a G11, camera is a QSI 683 and I took about 6x10 minute subs each of L, R, G B and H-alpha. I combined the H-alpha with the L by multiplying them and normalising the result by the square root of the product of their means - seems to be a good compromise. ONe thing I've niteced is the colours are slightly more yellow biased after uploading to astrobin, putting the original in Pixinisght next to the one on the web, there's a distinctly orange cast to the astrobin display. I didn't think there was any processing after it was uploaded? Anyway, h-res, orangey astrobin version here: http://www.astrobin.com/full/103964/B/
Constructive commentary welcomed!
cheers,
Andrew.
