This is NGC 2217, a lenticular galaxy located in the constellation of Canis Major, The Great Dog. It has a set of spiral arms tightly wound with a bluish colour. They form an almost circular ring around the galaxy. This blueish colour indicates the presence of hot, luminous young stars born out of interstellar gas clouds.Contrasting this is the central bulge and bar region. This area is golden/yellower in appearance as it contains older stars. I especially love the two thin tight arms around the central bar. It looks like an eye looking back.
I didn't find many renditions of this galaxy. I guess it's on the small side. I think it's an interesting object. Those almost circular ring arms are very cool.
