Anyway, I am not unhappy with this at this point, the processing was literally my first crack at RGB-HA-Oiii and I only had about an hour to work on it. Real life intrudes! With any luck the mono cam arrives soon and I can redo the NB subs and then put a lot more time in to the process.

If noise is an issue increasing your SNR by binning your mono channels or shooting more subs and dithering will all help greatly. Regarding noise reduction methods there are many good programs out there. Unfortunately Topaz is definitely not one of them. I would also recommend not to sharpen your nebulosity after you have removed the stars. You need the stars for proper sharpening to take place. Otherwise you'll introduce artefacts and details that are not consistent with the original starfield resolution. I see too many pictures lately with these problems. This one is not one of them.
