M 83 - the Southern Pinwheel Galaxy

M83 

 

Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation Hydra.
This is a massive, grand design spiral galaxy. The morphological classification of NGC 5236 is SAB(s)c, where the 'SAB' denotes a weak-barred spiral, '(s)' indicates a pure spiral structure with no ring, and 'c' means the spiral arms are loosely wound.  (wiki)

Photographed from Mirtos / Crete during our short spring holiday. My guider (Lacerta MGEN) unfortunately died already on the way there and even the weather was not too co-operative..
