Recorded (1901) by
Williamina Fleming (87)
A magnitude 11(?) star in Dorado (RA 04 57 08.8, Dec -66 23 25)
Although in the direction of the Large Magellanic Cloud, merely a foreground star in our own galaxy.

IC 2116 ("in" the Large Magellanic Cloud)
Recorded (1901) by
Williamina Fleming (88)
A magnitude 11(?) star in Dorado (RA 04 57 16.2, Dec -66 23 21)
Although in the direction of the Large Magellanic Cloud, merely a foreground star in our own galaxy.

IC 2117 (in the Large Magellanic Cloud)
Discovered (1901) by
Williamina Fleming (89)
An emission nebula in Dorado (RA 04 57 14.3, Dec -68 26 32)
A 'knot' of nebulosity (and most likely, of stars lighting up that nebulosity) in NGC 1770. Apparent size 1.8 arcmin?

IC 2118 (probably =
NGC 1909), the Witch Head Nebula
Discovered (Dec 20, 1786) by William Herschel (and later listed as NGC 1909)
Discovered (Jan 16, 1891) by Max Wolf (and later listed as IC 2118)
A reflection nebula in Eridanus (RA 05 04 54.0, Dec -07 15 00)
Dust in the region near the first magnitude star Rigel, which is to the left of the area shown here, scatters the star's blue-white light in the same way that our atmosphere scatters sunlight, lighting up what would otherwise be only a dark patch silhouetted against the starry background. Rigel and the nebula lie about 800 light years from us. (Note: Although this is probably the same object listed as NGC 1909, that identification is less certain than for the IC entry; so despite the usual preference for using NGC designations, the nebula is usually referred to by its IC designation.)

IC 2119 (= PGC 16759)
Discovered (Nov 30, 1897) by
Lewis Swift (XI-74)
A magnitude 13.6 spiral galaxy (type Sb??) in Lepus (RA 05 06 50.9, Dec -20 20 45)
Apparent size 1.1 by 0.7 arcmin?

IC 2120 (= Comet 113/P Spitaler 1890)
Recorded (Dec 8, 1890) by
Guillaume Bigourdan (262)
A misinterpreted observation in Auriga (RA 05 19 10.3, Dec +38 11 06)
Per Corwin, this is a duplicate observation of the comet Bigourdan observed an hour and a half earlier, but he did not organize and catalog his nebular observations until years after the fact, and apparently missed the duplication, leading to the IC entry. (There are several cases in which "lost" NGC/IC objects are suspected of being observations of cometary or other "ephemeral" phenomena, but due to the duplicate observation, this is one of the most obvious.)

IC 2121 (= PGC 17110, and probably not =
IC 408)
Discovered (Dec 26, 1897) by Lewis Swift
A 12th-magnitude lenticular galaxy (type SAB0/(s)a? pec) in Lepus (RA 05 19 44.8, Dec -25 03 53)
Per Dreyer, IC 2121 (Swift list XI (#75), Howe, 1860 RA 05 14 01, NPD 115 12.7) is "most extremely faint, small, round, very difficult, 7th magnitude star 14s west, 3.6 arcmin south". The position precesses to RA 05 19 45.0, Dec -25 03 57, right on the galaxy, and the starfield exactly confirms the identity. (See IC 408 for a discussion of the almost certainly incorrect suggestion that it might be the same as IC 2121.) Apparent size 2.2 by 1.4 arcmin.
