Object name: IC0603
IC 603 is a ring galaxy in Sextans about a quarter of a billion light-years distant. It is classed as (R)SB(r)a: so is a barred spiral with two ring structures, and outer and inner ring. The outer one is very slightly blue while the inner one quite red. At about the same redshift and thus likely about the same distance is MCG-01-26-040 another galaxy with a ring like structure though that isn't mentioned in its classification system. It is listed as simply SBa. I'd say SB(r)a as the arms off the bar form a pseudo ring in my image at least. This is an area of the sky not covered by the Sloan survey so I expected to find little on the other galaxies in the field but was pleasantly surprised to find it seems rather well covered. While many of the galaxies are listed only by their positions in various catalogs some have catalog names that aren't just coordinates. Those are listed by their LEDA number or other designation when available. It was discovered by Stephane Javelle on April 10, 1893.
