We've had a closer look now. You are right that there is an issue to be fixed: a handful of the brighter stars have assymetrical green fringes, especially a green smudge toward bottom right of the star. It's not overall colour balance: reducing the green channel strength hopelessly messes up the colour balance for the image as a whole. Looking at the faintest stars, the registration of R, G, and B on the great bulk of fainter stars seems pretty accurate, so it's not a registration error. We could apply a finger-painting cosmetic fix, but that would be wicked and sinful. We throw up our hands in dismay. Please avert your gaze, and enjoy the galaxies!
