IC 4050
Recorded (Mar 21, 1903) by

IC 4051 (= PGC 44828)
Discovered (Apr 12, 1891) by
Guillaume Bigourdan (308)
A magnitude 13.6 elliptical galaxy (type E4?) in Coma Berenices (RA 13 00 51.6, 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 a recessional velocity of 8795 km/sec, IC 4051 is about 410 million light years away. Given that and its apparent size of 0.9 by 0.5 arcmin, it is about 110 thousand light years across.

Recorded (Mar 21, 1903) by

A pair of stars in Canes Venatici (RA 13 01 35.8, Dec +36 35 39)

IC 4079 (= PGC 1585609)
Discovered (Jan 27, 1904) by
Max Wolf
A magnitude 16.5 spiral galaxy (type Sa? pec) in Coma Berenices (RA 13 01 56.8, Dec +19 14 54)
Per Dreyer, IC 4079 (= Wolf list VI #155, 1860 RA 12 55 03, NPD 69 59.7) is "very faint, very small, attached to next", 'next' referring to IC 4080, which is just northeast of IC 4079. Wolf's original paper adds that there is a 14th magnitude star preceding the object, and that the star's position is what he measured. (See IC 4080 for a further discussion showing that the identifications of IC 4079 and 4080 are certain.) Apparent size 0.35 by 0.2 arcmin. (Shown in Wikisky as PGC 1585609)

IC 4080 (= PGC 3800908 + PGC 4538148)
Discovered (Jan 27, 1904) by
Max Wolf
A pair of galaxies in Coma Berenices
PGC 3800908 = A magnitude 16.2 spiral galaxy (type Sa? pec) at RA 13 01 57.7, Dec +19 15 12
PGC 4538148 = A magnitude 16.7 spiral galaxy (type S?) at RA 13 01 58.3, Dec +19 15 21
Per Dreyer, IC 4080 (= Wolf list VI #156, 1860 RA 12 55 04, NPD 69 59.6) is "faint, very small, 14th magnitude star 0.3 arcmin to west, 15th magnitude star to southeast". The 14th magnitude star is clearly the one mentioned in Wolf's notes for IC 4079, and his notes for IC 4080 add that the 15th magnitude star is 0.4 arcmin to the southeast of that object. These notes and Wolf's positions make it certain that IC 4080 is the pair of galaxies listed above, and IC 4079 is the brighter galaxy immediately to their southwest. Apparent size of PGC 3800908 is about 0.25 by 0.1 arcmin; apparent size of PGC 4538148 is about 0.14 by 0.1 arcmin.

IC 4093
Recorded (May 13, 1895) by

A lost or nonexistent object in Coma Berenices (RA 13 02 03.0, Dec +28 59 42)

IC 4094 (= PGC 2109709)
Discovered (Mar 21, 1903) by
Max Wolf
A magnitude 15.4 spiral galaxy (type SBdm?) in Canes Venatici (RA 13 01 58.7, Dec +37 47 42)
Per Dreyer, IC 4094 (= Wolf list V #179, 1860 RA 12 55 26, NPD 51 27.1) is "faint, very small, irregular figure, nuclear". The position precesses to RA 13 01 59.0, Dec +37 47 39, right on the galaxy listed above, so the identification is certain. (There is an apparent companion just to the south (PGC 4351761) that is sometimes mentioned as a possible part of the IC entry, so it is discussed immediately below; but there is nothing in the historical record to indicate that it should be thought of in that way.) Apparent size 0.45 by 0.3 arcmin.

A magnitude 16.5 spiral galaxy (type S?) in Canes Venatici (RA 13 01 58.9, Dec +37 47 24)
Very unlikely to be part of IC 4094 (which see for images), whose historical position would almost certainly be further south if PGC 4351761 had had any effect on Wolf's measurement. Apparent size 0.25 by 0.1 arcmin.
