Object Information                                            Imaging Details

M83, the Southern Pinwheel Galaxy, is a splendid spiral galaxy in the southern sky. At magnitude 8.5, it's easily within reach of modest telescopes, and with a diameter of 14 arc-minutes, it's about half the diameter of the Moon. M83 lies about 15 million light years away in the constellation Hydra.

M83 is easy to spot through a modest telescope. Observing the galaxy's details requires a reasonably large telescope.

I imaged this object at the 2009 Texas Star Party (near Fort Davis, Texas). Sky transparency was excellent, seeing was average to good.
