About this image

This image of the large spiral galaxy, Messier 83 was taken by Trevor from his home observatory in South Australia between May and July 2020 at varying times through the evenings.  The image was processed using PixInsight and PS CC 2017.

Messier 83 is known as the "Southern Pinwheel Galaxy" and is approximately 15 million light-years away on the borders of Hydra and Centaurus.  It was discovered by Nicolas Louis de Lacaille on February 23, 1752 at the Cape of Good Hope.
