It just needs more exposure time to improve the signal to noise ratio.
Perhaps a slight non alignment of the various masters in the registration step? Or red has slightly larger stars in which case do a mild deconvolution on the red master. Some stars look a bit mishapen but the galaxy seems sharp.
I know we've had lots of wet weather but galaxies, no matter what your setup, are a many hour exposure type image.

Thanks Greg. Yes, the stars have my signature assymetrical flaring in places along with some imperfect alignment (tracking but also meridian flipped images with flaring in opposite direction). But that's how you know its a "Robbo original"
. Confession: I did minimise them in processing slightly to try and reduce distraction looking at the galaxy. I think I've got a bit too much blue/green in my (err... the galaxy's) halo too. Will have another one evening when trust what I'm seeing.
As for time, 2 big trees in my backyard conspire to make objects near the meridian difficult - about 2.5hrs max visible time each night, so with setup/pull-down over many sessions it gets tedious. Although this image is 3hr 20mins of data, there was probably another 40-50% thrown away for gear problems, wind, clouds tracking etc over these sessions alas.
