Thanks Russ. I've found that imaging with a DSLR in the summer is a sure way to introduce thermal noise .. and my skills in PS aren't up to the task of removing it. A cooled camera has made it so much easier.
Having said that, there's more to come on this image once I get some more data (hopefully tonight)
Here's a link to the larger version in Astrobin.
