IC 983, NGC 5490 and PSN J14095513+1731556: an image (19 Feb. 2015)
Recently, while following-up a recently discovered optical transient, PSN J14095513+1731556 – turned out to be a supernova – we spied a nice spot of the sky where, all around the supernova and its host galaxy (NGC 5490), there are many other wonderful cosmic islands.
In particular, the field is dominated by the beauty of IC 983, a stunning, elegant spiral galaxy, making a nice couple with IC 892 (at hour one in the picture above) and, a more distant on the right, with NGC 5490 (hosting the mentioned supernova). The two IC objects are also listed as Arp 117, while the small spiral between IC 983 and NGC 5490 is NGC 5409C, also known as Arp 79.
Distance to IC 983 and NGC 5490 is estimated in the range of 200/250 millions of light years.
This image above comes from the average of fifteen, 300-seconds exposures, unfiltered, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project.
