The Stephan’s Quintet

The Stephan’s Quintet are five galaxies, NGC 7317, NGC 7318A, NGC 7318B, NGC 7319 and NGC 7320 of which the first four are also physically close and interacting with each other while NGC 7320 is only prospectively close to the others.
It is not an easy subject to photograph, the five galaxies have surface magnitudes between 13.00 and 13.90 and with apparent size between 0.6′ and 2.3′ and the exposure time was only one hour but they are one of the most famous astronomical picture.
