Messier 83 (also known as the Southern Pinwheel Galaxy, M83 or NGC 5236) is a barred spiral galaxy approximately 15 million light-years away in the constellation Hydra. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars. Six supernovae (SN 1923A, SN 1945B, SN 1950B, SN 1957D, SN 1968L and SN 1983N) have been observed in M83.

This was the first image taken with my new set-up at Coonabarabran. It is a LRGB image with integration times of 3 hours each of L, R, G and B. All subs are 5 minutes each with L unbinned and RGB binned x2.
