Linear Fit + narrowband normalization in Pixinsight will get you roughly on track with the same color.
This data was a fun project shot when I was using my RC at the native focal length with my present imaging train. It comprises of about 66 hours of integration time including the RGB portion which I've not included here. It's easily over 60 hours in narrowband alone.
Focal length: 1628 mm
Pixel Size: 3.76
