Nice clean image Tim
Did you intentionally leave the main cluster core area with a bluish tinge , possibly your filter doing that ?
Stars are nice and round too
Well done
You have an exceptional image that you should be most proud of.
It is a deceptive target but not easy to do it justice and you have done it justice.
You must print the image and hang it in pride of place.

Thanks for the comments. I prefer a level of brightness that allows me to "see into" the cluster core. The colour selection is my own idiosyncratic preference.
