I attempted this a while ago in narrowband, which was fairly challenging experience for me. Managed to get some rgb last week.
The first shot is an attempted HaRGB blend and the second pure RGB. My setup has had some pretty bad tilt issues while far from perfect this is an improvement so happy with that. I also bought RegiStar - wow what an effective program. The HaRGB blend doesn't really appear much different perhaps I need to try some of the other blending options.
Anyway I love this little target, it looks like a jewel, i'll probably do repro fiddling with blending methods and maybe even add some O3 data I have in there and try and bring more of the shockwave out

Any pointers appreciated especially on which blending methods I should use in registar.
