NGC 800 = (PGC 7740)
Discovered (Oct 9, 1885) by Lewis Swift (2-17)
A 13th-magnitude spiral galaxy (type SA(rs)c) in Cetus (RA 02 02 11.8, Dec -00 07 51)
The second Index Catalog lists a corrected 1860 RA (per Howe) of 01 55 92. Paired with NGC 799. Based on recessional velocity of 5965 km/sec, about 265 million light years away. Given that and apparent size of 1.04 by 0.68 arcmins, about 80 thousand light years in diameter.
