Thanks all,
Narayan, for some reason the orange stars on the right and left had their colour before I really got into the processing but the other stars below which are also orange or red stars did not show this as well. I need to investigate why this occurred, and yes I knew this was an issue.
Peter, I knew you would see the flaws that were there. To be fair not all the stars have rings around them. Some of the blue ones have darker blue than others.
Yes the blue/purple tinge is enhanced but even Wolfgang Promper has blue showing where mine is.

Maybe the purple tinge needs backing off a bit.
Are you saying the core of my image is too bright or should it be brighter? Not sure what you mean here. I think you mean that it should be brighter than it is at present that having it all even here is causing it to look wrong.
Appreciate the critique, always good to improve. I thought this was a vast improvement over the last rendition of this image though.
Thanks all once again.
