Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, pL, irregular triangular figure, resolvable."
John Herschel recorded it as "pB, R, gbM. Very visible in strong moon light."
Recorded in "Observations of the Southern Nebulae made with the Great Melbourne Telescope".
See the discussion of Lithograph M.3.28 for the details.
Observations with the 72-inch f/8.8 speculum telescope at Birr Castle noted "close double nebula [NGC 1888 & NGC 1889]."
! pB 2' long, mE 145deg; spiral seen edgewise with suggestion of absorption and no nucleus; 20'' n.f. its centre there appears to be a vS, vB globular nebula, unsymetrically placed with regard to the spiral and having no connection with it. See Pub. Lick Obs., Vol 13. The PA is wrongly given as 60deg.
Together with NGC 1889 listed as No. 123 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "faint parallel feature on opposite side from SO galaxy."
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads EON,BM,EQDKLN.
M-02-14-013 & Arp 123
05 22.6 -11 30
13: fairly faint, very elongated 3:1 NW-SE streak. Forms a contact pair with N1889 just NE of the center.
8: very faint, small.
Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty small, elongated, brighter in the middle at 135X. A pretty faint star is involved on the west side."

f/13.7, 35mm Televue Panoptic (5' fov, 812x)
Interacting galaxies, the larger edge-on galaxy has the smaller round galaxy sitting right on its central bulge. Not much other detail, but a very nicely framed pair.
