Go the Guinness  ... actually, we have a boutique brewery in our apartment building called Bentspoke, they make some 18 different beers and cider and my favourite is called Big Nut a really full flavoured dark ale style beer...absolutely magic, I could eat it (actually I have slow cooked lamb shanks in it - maaaw yum!), if you are ever in Canberra please let me know and I would love to shout you a few (7.5% alcohol though so no processing afterwards  )

The funny stars are orthog.... whatever probs I think, minor, PS will fix it. Yes, im up for 18 beers, that would be processing havoc methinks, worth a try.

The 20 hours has produced an extremely smooth, grit-free result. No having to guess about faint detail. Your optical train, guiding, etc are working flawlessly. We had lots of fun exploring the tiniest details, especially in the fainter areas.
Minor: There's a very slight tendency toward posterization or blockiness of some of the brighter detail. Perhaps it's getting too stretched and then you're unstretching it a bit. You might be able to protect the bright stuff.
Hubble palette: I can see why you might want a simple H-alpha OIII blend to look natural colour. You can do that. There's a very plausible mapping that makes sense. But with Hubble tri-colour, there's no way that they can make it look "natural" and still preserve the astrophysical information and meaning in the SII (or NII) channel. H-alpha and SII (and NII) are all almost precisely the same colour!
Best,
Mike and Trish

Thanks Mike. The colour will be with SII, Ha and OIII. In this case, "modified hubble" is not bicolour, just that the 3 NB filters are mapped differently. The blockiness is a worry. ahh, haddnt thought of that, overstretching and then unstretching, I do that sometimes, interesting.
