Very nice Roger. The colour of the Crescent is unusual but nice. You should try the EZ processing star reduction script, would de-emphasise the bright sparks with minimal effort.
I agree it is an unusual colour. what subs did you actually take and how did you combine them?

i used star de-emphasizer in PI slightly as will reprocess when more data.

That's an excellent Crescent, Roger! Lovely framing and looks like floating among the stars.
