NGC 7023 - The Iris Nebula
I added another hour and a half of 4 min. subs to this image on Saturday. I was actually surprised at how little of a difference it made lol. Still though, I think this is the best version yet. I am done with this object until next year, as I have spent about a month imaging and processing it!

I'd be happy w/that, looks good. Besides the dust (nice processing), I like how you pulled out that nebulosity on the lower part of the neb. Marc

You may be right Russ, although it still seems to be a bit noisy. It may be because of the drastic temperature change in my last imaging session. The darks were taken at about 15c and the first 10 or so lights at 20c. But thank you for the comment!

Very nice. Perhaps the extra time got you a little less noise...
Regardless, it's a nice deep shot. You did a nice job of pulling the dust up out of the background.
