IC 4150
Recorded (1904) by
Max Wolf
A 17th-magnitude star in Coma Berenices (RA 13 04 13, Dec +21 59 14)

IC 4151 (= PGC 2088237)
Discovered (1903) by
Max Wolf
A 17th-magnitude pair of galaxies in Cane Venatici (RA 13 03 59, Dec +36 51 26)

Based on recessional velocity of 21870 km/sec, about 1 billion light years away. Given that and apparent size of 0.25 by 0.18 arcmin, about 70 thousand light years across. The southwestern (lower right) galaxy is referred to as IC 4151 NED01, and the northeastern (upper left) as IC 4151 NED02, as shown in the image below.
