De Vaucouleurs Atlas Description:

This galaxy is an excellent outer-ringed system that resembles NGC 1291 to a great extent. The inner regions include a very bright inner lens (l), a fairly prominent bar, and a strong secondary bar oriented at a large angle to the primary bar (Buta and Crocker 1993; Erwin 2004). The outer ring is diffuse and very well-defined, and is completely detached. The basis for the S0/a classification is the two conspicuous spiral arms that break from the outer ring region. These arms are very knotty and seem to be defined by star forming regions. They are unusual to see in what would otherwise be an SB0+ system.
