Barred Spiral Galaxy NGC 2608 (aka Arp 012):

Dreyer's description in the New General Catalog (NGC):

"Faint, very little extended, much brighter middle, resolvable, but mottled."

Quote from The Deep Sky Field Guide to Uranometria 2000:

"Two asymmetric arms very high surface brightness. 'Nucleus may be double, or superposed star' (Arp)".

NGC 2608 in the constellation of Cancer is a very elongated galaxy with a bright core. It is in Arp's class: "spiral galaxies with split arms".

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 2608 is 112 million light years, with a diameter of about 75,100 light years.
