The Southern Pinwheel Galaxy also known as M83 is a barred spiral galaxy, like our Milky Way, but less than half the Milky Way's size. It is located approximately 14.7 million light-years distant in the eastern section of the constellation Hydra, and, from Southern and Equatorial latitudes, is visible with binoculars, appearing under dark skies as a patch of light with a brighter center. For mid-latitude northern hemisphere observers, the galaxy can be a difficult object as it never climbs particularly high above the southern horizon. This LRGBHa image was taken remotely, 5 minute exposures for each filter, using the Sliding Springs, NSW Australia, Observatory's 430 mm PlaneWave CDK imaging platform (T17), at 1:00 AM local time. Post-processing was with Nebulosity and GIMP.
