IC 1750 (= PGC 7266)
Discovered (Dec 21, 1903) by
Stephane Javelle (899)
A magnitude 14.6 spiral galaxy (type S0/a?) in Pisces (RA 01 56 18.7, Dec +04 04 35)
Based on arecessional velocity of 5655 km/sec, IC 1750 is about 265 million light years away. Given that and its apparent size of 1.25 by 0.3 arcmin, it is about 95 thousand light years across. (Note to self: All current protocols followed.)

IC 1751 (=
NGC 741 = PGC 7252)
Discovered (Dec 13, 1784) by William Herschel (and later listed as NGC 741)
Also observed (date?) by John Herschel (and later listed as NGC 741)
Discovered (Nov 26, 1897) by Lewis Swift (and later listed as IC 1751)
Also observed (Nov 24, 1899) by Herbert Howe (and later listed as IC 1751)
An 11th-magnitude elliptical galaxy (type E0??) in Pisces (RA 01 56 21.0, Dec +05 37 44)
Historical Identification: Per Dreyer, IC 1751 (Swift list XI (#28), Howe, 1860 RA 01 49 03, NPD 85 03.6) is "pretty bright, pretty small, round, 9th magnitude star to northwest". Swift states that the nebula is located at 1900 RA 01 50 45, Dec +05 11.2, and is pretty faint, pretty small and round, with a 9th magnitude star "near" to the northwest. Howe states that the nebula is at 1900 RA 01 51 08, Dec +05 08.3, and the 9th magnitude star is 7 seconds of time west and 1.6 arcmin north of the nebula. Swift's position is (as was often the case) relatively poor, being well to the west of Howe's, but the reference to the 9th magnitude star makes it certain that they observed the same nebula. As usual, Dreyer used Howe's micrometric measurements for the IC2 position, which precesses to RA 01 56 21.4, Dec +05 37 38, nearly dead center on NGC 741, and Howe's accurate position for the 9th magnitude star makes the identification of IC 1751 as a duplicate of NGC 741 absolutely certain. Despite that PGC 7250, the faint galaxy to the north of NGC 741, is often misidentified as IC 1751, so it is discussed immediately below.
Discovery Notes: Since the position of IC 1751 and the 9th magnitude star so perfectly agree with those for NGC 741, its separate listing in the IC2 must have simply been due to an oversight.
Physical Information: Given the duplicate entry, see NGC 741 for anything else.

Discovered (Sep 29, 1897) by Lewis Swift (and later listed as IC 1759)
Discovered (Nov 17, 1897) by Lewis Swift (and later listed as IC 1760)
A magnitude 12.9 spiral galaxy (type SA(rs)bc?) in Fornax (RA 01 57 55.5, Dec -32 59 14)
Per Dreyer, IC 1760 (= Swift list XI (#30), 1860 RA 01 51 18, NPD 122 41.5) is "extremely faint, pretty small, round (PD may be 123°)". Per Corwin, Dreyer's query about the NPD is due to the fact that Swift's original notes included "Cordoba 681 southwest", which would be impossible if the NPD was 122 degrees, because Cordoba entries in that range of right ascension are numbered in the 700's. As it turns out Cordoba Durchmusterung (CD) -33 681 is to the southeast of the galaxy, not the southwest, but the reference to the star confirms its identification; and as it happens, its equality with IC 1759, which see for anything else. (There is more to discuss historically, but that will be covered in the next iteration of this page.) Unfortunately, the ESO catalog misidentifies IC 1760 as PGC 7357, and as a result so does the NED, so that object is listed immediately below.

Discovered (Dec 7, 1893) by Stephane Javelle (and later listed as IC 217)
Discovered (Oct 12, 1896) by Lewis Swift (and later listed as IC 1787)
A magnitude 13.6 spiral galaxy (type Scd?) in Cetus (RA 02 16 10.5, Dec -11 55 37)
Per Dreyer, IC 1787 (Swift list XI (#37), 1860 RA 02 09 24, NPD 102 36.2) is "extremely faint, very much extended, between 2 stars east and west, 8th magnitude star to northeast". The position precesses to RA 02 16 12.0, Dec -11 57 03, only an arcmin and a half south of the galaxy, and the perfect description of the nearby starfield makes the identification certain (for an image, see IC 217). As noted by Corwin, Javelle and Swift's positions and descriptions are sufficiently similar that Swift or Dreyer should have realized that Swift's XI-37 was IC 217 (the right ascensions are identical, the declinations differ by less than an arcmin, and both noted its considerable elongation), but neither did, so the galaxy ended up with duplicate IC entries.
