Hi all,

I could say "better late than never", eh?

I collected and processed HaRGB data for the Rosette Nebula back in November
2006:

In 2008, I gathered SII and OIII data for this nebula. I never got around to
processing this data until recently, thanks to the current run of bad weather. Granted, I have lots of data awaiting processing on top of this.

Anyways, here is the end result of a few days' worth of processing the Hubble Palette version of the data:

Nice job Eric. I guess I'm not the only one with cloudy skies.

Thanks for the comments!

I got some comments elsewhere on the background, so I thought I'd double-check my process flow. I may have found where I might have messed up a bit. In stretching I found some hidden gems in the background.

Here's the stretched version. This time I did not dim the background, as in looking at this I do see some dim details coming out. Please let me know how it looks, especially if I've gone too far.
