I used some RGB data colleted way back in 2013 (see
here), and combined it with H-alpha and OIII data from my recent image (see
here). The NB data was blended on each channel and also on a synthetic luminance, as follows: (Lsynth+Ha+OIII)(R+Ha, G+OIII, B+OIII).
The result shows much better star colors, and a somewhat softer but more natural image, compared to the NB version.
