DETAILS | NGC1808 is a ringed weakly barred spiral, Seyfert II type galaxy. 2MASXi J0507556-373241 is an Infra Red Source. This region (arrowed) produced supernova SN 1993af. This image has undegone some digital development to enhance the structure of the galactic core. AM 0505-374 NED02 and ESO 305-IG 010 NED02 are each part of a pair of galaxies. |
