Description M83 is one of the best face on spirals in the sky and is about 15 million light years distant.  It is sometimes called the "thousand ruby" galaxy because of the many prominent hydrogen alpha regions.  Visually it is a large ellipse about 7' x 5' easily visible in small telescopes.  Some hint of the spiral structure can be seen in 20cm.
