Arp Peculiar Object Number 159 - Disturbed Galaxy With Interior Absorption
NGC 4747 (PGC 43586 = Arp 159)
Discovered (Apr 6, 1785) by William Herschel
A 12th-magnitude spiral galaxy (type SBcd?) in Coma Berenices (RA 12 51 45.4, Dec +25 46 26)
Apparent size 3.3 by 1.3 arcmin? Used by the Arp Atlas as an example of a disturbed galaxy with interior absorption.

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.
Flat field and dark subtract calibration frames. Combined Stack of three images of 210 seconds each unfiltered and unbinned. CCD operating temperature: -42 degrees. Image acquisition and processing: CCD Soft v5, TheSky6 Professional and Mira Pro v7. December 27th 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_arp159.jpeg
