Beautiful image!
Which software are you using to process the data?
I can't remember whether it's DSS or Registax (probably both) but there are colour gradient filters or something I can't remember the name of which you can use to automatically balance the captured data or manually adjust it to your own liking.
As someone with red green colour blindness my images always end up with a certain blue tinge to them but thankfully I have a son with excellent sight and he corrects my imbalance for me.
A few links I didn't yet read which may be a little helpful (and later to me too hopefully):
