Here's 30 minutes on M83, of just Lum and H-a, combined
It'll be LRGB-Ha ONE day, but for now, at least there's some colour in it.
Focus shift occured due to temp drop/acclimitisation half way through, hence big stars and lack of fidelity. You can still see a lot of the surrounding faint fuzzy GX's though (bottom left, bottom right, the usual 2 directly above M83).
