A very nice image. Lots of detail and colours look pretty close ( a few stars seem to have too much green in them). The galaxy looks fabulous.
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.
