Arp 2

  This is another of the LSB Spirals.  It is peculiar by almost any definition.  To me, it appears to have an incipient bar running nearly N-S.  The Atlas notes say "low surface brightness dwarf.  Large bright knot in arm appears almost stellar".

The positive image is one of the very few to which I applied Background Smoothing.  The image was taken on a less than perfect night -- slightly hazy -- and Background Smoothing did eliminate a lot of noise, at the  cost of smudging out some of the fine detail.  The negative image was not smoothed.

I saw four very bright Perseid meteors during my night of imaging.
