Nicely done, Malcom. All the objects that you have listed including the PN and cluster NGC 2423 at about 2 o'clock are crystal clear.
You've got good colour in the bright K0 class star toward about 7 o'clock. Although most open cluster stars are white or blue-white, the SAO and PPM catalogues show a handful of faint orange stars in M47. You might perhaps be able to bring out more colour in the stars with different, gentle processing, and then combine the two versions.
Best,
Mike
