NGC 4565 Galaxy in Coma Berenices

This is one of the finest "Galaxy-Needles" in the heaven above, but it has a huge disadvantage for telescopes in the far south: located far north at a declination of +26° it suffers from a lot of atmospheric dispersion if beeing photographed at the CTIO (-30° south). 

NGC4565 is the brightes member of the Coma I cluster at a distance of 42.7 ± 12 million lightyears.Its apparent size of nearly 15 arcminutes and its brightness (10.4mag) makes it an easy object for telescopes of all sizes.

As already mentioned:it is one of the finest edge-on-galaxies and is suggested to be a barred spiral.It was first seen in 1785 by William Herschel.
