Southern Pinwheel Galaxy (M83)

Image of M83 taken using the Telescope Live CHI-2 (ASA500N) telescope.

Messier 83, also known as the Southern Pinwheel Galaxy, is a barred spiral galaxy located in the southern constellation Hydra, approximately 15 million light-years away from Earth. The galaxy appears face-on when viewed from Earth.

Messier 83 was nicknamed the Southern Pinwheel Galaxy because of its prominent, very well defined spiral arms (with several HII regions), which give the galaxy an appearance similar to the famous Pinwheel Galaxy (M101), located in Ursa Major.

If you enlarge this image, you see plenty of "small", more distant, galaxies...

Total exposure time 160 minutes. 8 subs of 300s with each filter (LRGB)
