Another Go at M83. I had an issue with mistaken filter position assignment in the acquisition software. This wasted me some frames (RGB), thus this image has less than optimal amount of RGB data. Next year I'll give it another try.

"Messier 83 (also known as the Southern Pinwheel Galaxy, M83 or NGC 5236) is a barred spiral galaxy[7] approximately 15 million light-years away in the constellation Hydra. In the Catalogue of Named Galaxies, it is called Corallium Hydrae, or the coral galaxy.[8] It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars.[9] Six supernovae (SN 1923A, SN 1945B, SN 1950B, SN 1957D, SN 1968L and SN 1983N) have been observed in M83. Its nickname of the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy." Source: Wikipedia
