The nicest image you have done Roger. 

Just need to sort out that miscreant green filter.  Are you 100% sure it was in focus? 
I think it must have been because you have a problem every time with the green stars being larger than the Red and blue, and I am sure you wouldn't coincidentally get it to be the only one out of focus every time.

You've done an excellent job on that one.  It's one of your best ones.  I'm sure the dark skies of Kelling had a lot to do with the success.  Images from dark skies are so much easier to process.
