IC 800 (= PGC 41763)
Discovered (Apr 22, 1892) by Stephane Javelle (219)
14th-magnitude barred spiral galaxy (type SB(rs)c pec?) in Coma Berenices (RA 12 33 57, Dec +15 21 17)
Based on recessional velocity of 2325 km/sec, about 100 million light years away. Given that and apparent size of 1.5 by 1.0 arcmins, about 45 thousand light years in diameter. |

Discovered (Sep 8, 1900) by Arnold Schwassmann (and later listed as IC 3672)
IC 810
Discovered (May 6, 1888) by Lewis Swift (VII-24)
IC 811 (= NGC 4663)
Discovered (1882) by Wilhelm Tempel (and later listed as NGC 4663)
Discovered (May 13, 1888) by Guillaume Bigourdan (176) (and later listed as IC 811)
IC 812
Discovered (May 15, 1893) by Stephane Javelle (752)
IC 813
Discovered (Apr 6, 1891) by Rudolf Spitaler (20)
IC 814
Discovered (May 10, 1893) by Stephane Javelle (753)
IC 815
Discovered (Apr 23, 1892) by Stephane Javelle (223)
IC 816
Discovered (May 5, 1888) by Lewis Swift (VII-25)
IC 817 (= IC 3764)
Discovered (May 5, 1888) by Lewis Swift (VII-26) (and later listed as IC 817)
Discovered (Feb 20, 1900) by Arnold Schwassmann (and later listed as IC 3764)
IC 818
Discovered (Mar 18, 1892) by Rudolf Spitaler (50)
IC 819 (= NGC 4676) (with IC 820 = The Mice)
Discovered (Mar 13, 1785) by William Herschel (and later listed as NGC 4676)
Discovered (Mar 20, 1892) by Rudolf Spitaler (51) (and later listed as IC 819)
Herschel observed the two galaxies as a single "possibly bi-nuclear" nebula, while Spitaler observed them as separate objects, leading Dreyer to give the separate nebulae individual IC listings, despite the pair already being cataloged as Herschel's NGC listing.
