Hi Eric,
it's still quite green to the background and also there is a redish ring about the half way point out and around from the centre which is possibly some sort of light reflection effect from a filter/ corrector....
I tried lots of things just quickly with your jpg image to remove this... using PixInsight's 'background extraction routine' but found the ring remained. Also tried Gradient Exterminator and this didn't get rid of the ring either.
What I suggest is for you to start taking flat fields, this should get rid of any optical effect and flatten your background so things will be much even and neutral. Will make getting rid of light gradients much easier.
Sky flats are relatively easy to do... and if your handy enough, a light box will certainly be even better.
Always takes time to sort out issues with new gear, but I'm sure you will over come this little issue.
The object's colour itself looks great!!
All the best
Rich
