NGC 3718, NGC 3729 and Hickson #56

As part of Herschel 400 I made pictures of NGC3718 and it's compagnon NGC3729. NGC3718 (also known as Arp 214) is located in constellation Ursa Major and is about 52 million ly away from Earth. NGC 3729 is interacting with NGC 3718 on a distance of about 150.000 ly.

Next to NGC3718 a group of galaxies is visible. This is Hickson Compact Group (HCG) number 56 counting 5 galaxies. The Hickson Compact Group was published in 1982 by Paul Hickson. A well knows HCG is number 92 known as Stephan's Quintet.  See observation via this link.
