Really nice work, John.
The only suggestions I have would be firstly that you need flats There's some dust on the left. On the right edge there's a vertical light section which you can crop out and that can also help with background extraction algorithms from your program of choice.
Colour cast is also a bit off.
But all of that said, this is amazing especially for an unguided shot. Really well done, you should be proud of that.

As mentioned flat fielding will make it even better.
