Arp 9 (NGC 2523)

  This unusual barred spiral is in Arp's Split Arm class.  The split arm is quite obvious.  The Atlas note is "bifurcated arm does not start at end of bar".  The bright edge-on galaxy near west edge of the field is NGC 2523B.  The very strange little galaxy in the NW corner is UGC 4279. 

I was fighting thin clouds during the early exposures but it cleared nicely.
