I posted the Rosette here a couple of weeks ago but wasn't happy with it. So I re-imaged the Rosette again, trying to see why the last image was hazy.
The seeing seemed better this time, but the temperature of the camera was 30.5 degC!
Anyway, I think this is better than the last go at it (I stretched it far less).
I am now thinking that the haze is noise and possibly mismatched darks (temp mismatch).

I am kind of hoping that the target is simply very faint and that the uncooled camera at 30 deg doesnt take too kindly to its images being stretched much (thats when the haze starts!)
It definitely does have a relatively low surface brightness compared to other commonly imaged faint fuzzies Paul. That's still a very decent rendering though, especially for such high temps! Its just such a beautiful object, you have to have a go....!
Thanks Rob. yes it is lovely, thats why I gave it another go! I think Iwill get one more chance at it next new moon. Will try it with a Canon 350d modded and see what comes out!
Marc, yes not only the Ha but the Lum washed the red out a bit. I will have a play around with the saturation and get some red happening. Thanks very much for the feedback guys.
