NGC474 Galaxy in Pisces

NGC 474 is a shell elliptical galaxy discovered in 1784 by William Herschel. The most impressive structure given by it´s surrounding shells and tidal streams is maybe a result of interaction between NGC474 itself and the smaller galaxy next to it called NGC470 which are together known as Arp227. NGC467 is the galaxy to the top left.
