Thanks David,
I reprocessed it again using some LRGB subs of only 1 minute each which I copied & pasted in.
That gave me smaller stars & more star color.
No luminance was used from my DSLR.
This is only the QHY9 data.
A full frame version is here:

There is still some gradient but I got rid of most of it.
