IC 4050
Recorded (1903) by
Max Wolf
A double star (magnitudes 16 and 17) in Canes Venatici (RA 13 00 44, Dec +36 44 19).

IC 4051 (= PGC 44828)
Discovered (1891) by
Guillaume Bigourdan
A 14th-magnitude elliptical galaxy (type E5) in Coma Berenices (RA 13 00 52, Dec +28 02 34).

IC 4051 and NGC 4908 are often confused with each other (for instance, Wikisky and HyperLeda show each with the other's label). Part of galaxy cluster Abell 1656. Based on recessional velocity of 8795 km/sec, about 390 million light years away. Given that and apparent size of 1.0 by 0.9 arcmins, about 115 thousand light years in diameter.

Special care has been taken in labeling the wide-field image
Not all galaxies are labeled yet, but the ones that are, are correctly labeled
