Yet another go at M83, the Southern Pinwheel Galaxy. I think the small sensor of Atik 314L+ is quite sensitive, but unfortunately it gives a quite under sampled image. Maybe drizzling the image will yield a somewhat better result. This galaxy has a strong Luminance signal, but I find the colour balance to be quite tricky...
