NGC 523 (NGC 537 = PGC 5268 = Arp 158)
Discovered (Sep 13, 1784) by William Herschel (and later listed as NGC 537)
Discovered (Aug 23, 1862) by Heinrich d'Arrest (and later listed as NGC 523)
A magnitude 12.7 spiral galaxy (type Sbc) in Andromeda (RA 01 25 20.7, Dec +34 01 31)

Image... Cherryvalley Observatory (I83). Telescope: 0.2-m SCT & SBIG STL-1301E CCD Camera @f7.6. Image Scale 2.17 arcsec/pixel, Field of View 46 x 37 arcmins. Combined Stack of seven images of 300 seconds each unfiltered and unbinned. CCD operating temperature: -30 degrees. Image acquisition and processing: CCD Soft v5, TheSky6 Professional and Mira Pro v7. September 21st 2014.
Dr. Halton Arp originally compiled the Atlas of peculiar galaxies with photographs he made mainly using the Palomar 200-inch telescope and the 48-inch Schmidt telescope between the years 1961 to 1966. Original image can be found here: ned.ipac.caltech.edu/level5/Arp/Figures/big_arp158.jpeg
