That is a very good rosette!

If you want two simple hints for a very simple yet powerful improvement, in my very personal opinion and taste, try this:

1) Get rid of all the green. You download the "Hasta La Vista Green" plugin and use medium setting:

2) Add a Hue/Saturation adjustment layer and target magenta. Set it to zero. This will give you stars without the dreaded magenta tint (not that you have much of it, but still):

These are just my very personal taste "improvements", so take them at face value :) or not... 

Merry Christmas,

Thanks A.G and Per!  Per, I went ahead and did as you suggested and am happy with the results.  The stars are from RGB data I had from a DSLR, but those magenta "hues" still poked through, thanks for pointing them out and suggesting the correction.  

I appreciate your input,

Happy Holidays,

Steve

Very good. I have never done a Hubble Palette image so I can't make any intelligent comment but this looks deilcate and informative as well as beautiful.

No worries, Steve!

That's what a forum is for: constructive criticism.
