NGC 1850 (= OCL PGC 2802627, in the LMC)
Discovered (Aug 3, 1826) by James Dunlop
Discovered (Nov 2, 1834) by John Herschel
A magnitude 9.0 open cluster in Dorado (RA 05 08 45.5, Dec -68 45 40)

Historical Identification: Per Dreyer, NGC 1850 (= GC 1060 = JH 2780, Dunlop 170?, 1860 RA 05 09 25, NPD 158 55.8) is a "remarkable object, a globular cluster, very bright, large, a little extended, very much compressed middle, partially resolved, some stars seen". (Steinicke states = Dunlop 172.)
Discovery Notes: Dunlop 170? in Dreyer's entry means that Herschel thought Dunlop 170 might be his (JH) 2780 and listed it as such (with a question mark) in the GC, and as a result so did Dreyer in the NGC. (Steinicke states = Dunlop 172.) means it is now thought that NGC 1850 is actually Dunlop 172.
Physical Information: Apparent size 3.4? arcmin. In the Large Magellanic Cloud.

NGC 1851 (= GCL 9 = C73 = PGC 2802628 = ESO 305-SC016)
Discovered (May 10, 1826) by James Dunlop
Discovered (Oct 23, 1835) by John Herschel
A magnitude 7.2 globular cluster (type II) in Columba (RA 05 14 06.3, Dec -40 02 48)

Historical Identification: Per Dreyer, NGC 1851 (= GC 1061 = JH 2777, Dunlop 508, 1860 RA 05 09 30, NPD 130 12.3) is "a remarkable object, a globular cluster, very bright, very large, round, very suddenly very very much brighter middle, well resolved, clearly consisting of stars."
Discovery Notes: Dunlop 508 in Dreyer's entry means that Herschel felt certain that his (JH) 2777 was the same as Dunlop 508, listed it as such in the GC, and as a result so did Dreyer in the NGC. The lack of any other comment means that this is still the accepted identification of Dunlop 508.
Physical Information: Apparent size 11.2 arcmin, 12.0 kpc distant. Very eccentric orbit, well within 1000 light-years of center at perigalaxion, with an orientation that changes at every passage near the galactic center.

NGC 1852 (= an OCL in the LMC)
Discovered (Nov 6, 1826) by James Dunlop
Discovered (Dec 23, 1834) by John Herschel
A magnitude 12.0 open cluster in Dorado (RA 05 09 24.0, Dec -67 46 39)

Historical Identification: Per Dreyer, NGC 1852 (= GC 1062 = JH 2781, (Dunlop 171), 1860 RA 05 09 42, NPD 157 57.0) is "faint, pretty large, round, very gradually a little brighter middle".
Discovery Notes: (Dunlop 171) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1852 is probably the object recorded as Dunlop 171.
Physical Information: Apparent size 1.8? arcmin. In the Large Magellanic Cloud.

NGC 1853 (= PGC 16911)
Discovered (Dec 4, 1834) by John Herschel
A magnitude 13.0 spiral galaxy (type SBcd??) in Dorado (RA 05 12 16.0, Dec -57 23 58)

Historical Identification: Per Dreyer, NGC 1853 (= GC 1063 = JH 2779, 1860 RA 05 09 52, NPD 147 33.7) is "faint, small, much extended 45�, very gradually very little brighter middle, 11th magnitude star to northeast".
Physical Information: Apparent size 2.0 by 0.7? arcmin.

NGC 1854 (= "PGC 3517711") the bright core of GCL NGC 1855, in the Large Magellanic Cloud
Discovered (Aug 2, 1826) by James Dunlop (and later listed as NGC 1854)
Discovered? (Aug 2, 1826) by James Dunlop (and later listed as NGC 1855)
Discovered (Nov 23, 1834) by John Herschel
A magnitude 10.4 globular cluster core in Dorado (RA 05 09 20.0, Dec -68 50 51)

Historical Identification: Per Dreyer, NGC 1854 (= GC 1064 = JH 2782, (Dunlop 119), 1860 RA 05 10 02, NPD 159 01.2) is a "globular cluster, considerably bright, small, round, gradually brighter middle, 2nd of 3", but there is no mention of which of the numerous objects in the region are the 1st and 3rd of 3. The position precesses to RA 05 09 18.1, Dec -68 51 00, near the western rim of the cluster listed above, the description fits and there is nothing comparable nearby, so the identification is certain.
Discovery Notes: (Dunlop 119) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1854/1855 is probably the object recorded as Dunlop 119.
Discovery Notes 2: The double listing is not due to Dunlop, but to John Herschel, who reobserved all of Dunlop's objects (that is, the ones he could find). NGC 1854 refers to the brighter core of the stellar association, which was presumably observed by Dunlop (and by Herschel, in five separate observations of the region). NGC 1855 refers to a fainter outer "halo", which Herschel noticed on only one occasion. Since the two NGC numbers refer to different portions of the same object, they are in a sense identical, and are usually listed that way; but since NGC 1855 is probably a fainter outer region only noticed by Herschel, Herschel should probably receive credit for its discovery, even if it is still part of the same object.
Note About PGC Designation: For purposes of completeness LEDA assigns a PGC designation to almost every NGC object, regardless of whether they are galaxies or not; but in this case a search of the database for the PGC designation fails to return a result, hence the quotes around it in the title for this entry.
Physical Information: NGC 1854/55 is in the Large Magellanic Cloud, which is about 160 to 165 thousand light-years away. Given that and its apparent size of about 1.05 by 0.9 arcmin (from the images below), NGC 1854 is about 50 light-years across (as noted in the entry for NGC 1855, the entire cluster spans about 105 light-years).

NGC 1855 (a GCL in the Large Magellanic Cloud)
Discovered (Aug 2, 1826) by James Dunlop (and later listed as NGC 1854)
Discovered? (Aug 2, 1826) by James Dunlop (and later listed as NGC 1855)
Discovered (Nov 2, 1834) by John Herschel
The magnitude 10.4 core and halo of a globular cluster in Dorado (RA 05 09 20.0, Dec -68 50 51)

Historical Identification: Per Dreyer, NGC 1855 (= GC 1065 = JH 2783, (Dunlop 119) 1860 RA 05 10 08, NPD 159 00.6) is a "cluster, very bright, large, round, stars of 12th magnitude". The position precesses to RA 05 09 24.3, Dec -68 50 25, on the northeastern rim of the core of the globular cluster that is listed as both NGC 1854 (for its bright core) and 1855 (for the entire cluster, including the extended halo seen in DSS closeup images), the description fits and there is nothing comparable nearby, so the identification is certain, presuming that NGC 1855 represents the entire cluster, including the extended outer region, and NGC 1854 represents only the dense core of the globular cluster.
Discovery Notes: (Dunlop 119) indicates that Herschel was unable to identify Dunlop's object and did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1854/1855 is probably the object recorded as Dunlop 119 (though it is possible that Dunlop 119 is NGC 1858, instead).
Discovery Notes 2: The double listing is not due to Dunlop, but to John Herschel, who reobserved all of Dunlop's objects (that is, the ones he could find). NGC 1854 refers to the brighter core of the stellar association, which was presumably observed by Dunlop (and by Herschel, in five separate observations of the region). NGC 1855 refers to a fainter outer "halo" of about 5 arcmin diameter, which Herschel noticed on only one out of five observations of the cluster. Since the two NGC numbers refer to different portions of the same object, they are in a sense identical, and are usually listed that way; but since NGC 1855 is probably the fainter outer region only noticed by Herschel, Herschel should probably receive credit for its discovery, even if it is still part of the same object.
Note About Lack of PGC Designation: For purposes of completeness LEDA usually assigns a PGC designation for every NGC object, even if not a galaxy; but in this case there is no entry at all in LEDA, so there is no PGC designation, either.
Physical Information: NGC 1855 is in the Large Magellanic Cloud, which is about 160 to 165 thousand light-years away. Given that and its apparent size of about 2.2 arcmin (from the image below), it is about 105 light-years across.

NGC 1856 (= an OCL in the LMC)
Discovered (Sep 24, 1826) by James Dunlop
Discovered (Nov 3, 1834) by John Herschel
A magnitude 10.1 open cluster in Dorado (RA 05 09 29.4, Dec -69 07 40)

Historical Identification: Per Dreyer, NGC 1856 (= GC 1066 = JH 2784, (Dunlop 118), 1860 RA 05 10 20, NPD 159 18.0) is "bright, pretty large, round, gradually brighter middle, 12 seconds of time diameter in RA".
Discovery Notes: (Dunlop 118) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1856 is probably the object recorded as Dunlop 118.
Physical Information: Apparent size 1.8? arcmin. In the Large Magellanic Cloud.

NGC 1857 (= OCL 428)
Discovered (Sep 30, 1780) by William Herschel
Also observed (Feb 3, 1832) by John Herschel
A magnitude 7.0 open cluster (type II2m) in Auriga (RA 05 20 05.0, Dec +39 20 36)

Historical Identification: Per Dreyer, NGC 1857 (= GC 1067 = JH 350 = WH VII 33, 1860 RA 05 10 26, NPD 50 48.5) is a "cluster, pretty rich, pretty compressed, stars from 7th magnitude downward."
Discovery Notes: Herschel's published papers list the date of his first observation of WH VII 33 as Oct 18, 1786, but according to Steinicke, he had actually observed it (presumably during studies of double stars) on Sep 30, 1780, as shown above.
Physical Information: Apparent size 10? arcmin.

NGC 1858 (= an OCL and EN in the LMC)
Discovered (Aug 3, 1826) by James Dunlop
Discovered (Nov 2, 1834) by John Herschel
A magnitude 9.9 open cluster and emission nebula in Dorado (RA 05 09 55.0, Dec -68 53 54)

Historical Identification: Per Dreyer, NGC 1858 (= GC 1068 = JH 2785, (Dunlop 120), 1860 RA 05 10 37, NPD 159 03.7) is "bright, large, irregularly extended, binuclear, a cluster plus nebulosity".
Discovery Notes: (Dunlop 120) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1858 is probably the object recorded as Dunlop 120.
Physical Information: In the Large Magellanic Cloud.

NGC 1859 (= an OCL in the LMC)
Discovered (Dec 3, 1834) by John Herschel
A magnitude 12.3 open cluster in Dorado (RA 05 11 31.8, Dec -65 14 59)

Historical Identification: Per Dreyer, NGC 1859 (= GC 1069 = JH 2786, 1860 RA 05 10 59, NPD 155 24.8) is "faint, small, round, very gradually brighter middle, 7th magnitude star 6 arcmin to northeast".
Physical Information: Apparent size 2.0? arcmin. In the Large Magellanic Cloud.

NGC 1860 (= an OCL in the LMC)
Probably not observed (Aug 3, 1826) by James Dunlop
Discovered (Dec 30, 1836) by John Herschel
A magnitude 11.0 open cluster in Dorado (RA 05 10 39.6, Dec -68 45 08)

Historical Identification: Per Dreyer, NGC 1860 (= GC 1070 = JH 2787, Dunlop 172?, 1860 RA 05 11 22, NPD 158 55.6) is "faint, pretty large, round, very gradually brighter middle".
Discovery Notes: Dunlop 172? in Dreyer's entry means that Herschel thought Dunlop 172 might be his (JH) 2787 and listed it as such (with a question mark) in the GC, and as a result so did Dreyer in the NGC. However, it is now thought that Dunlop 172 is NGC 1850, and its questionable assignment to NGC 1860 is probably wrong.
Physical Information: Apparent size 0.8? arcmin. In the Large Magellanic Cloud.

NGC 1861 (= an OCL in the LMC)
Discovered (Nov 12, 1836) by John Herschel
A magnitude 13.2 open cluster in Mensa (RA 05 10 22.2, Dec -70 46 38)

Historical Identification: Per Dreyer, NGC 1861 (= GC 1071 = JH 2790, 1860 RA 05 12 02, NPD 160 56.9) is "extremely faint, pretty large, round, gradually a very little brighter middle".
Physical Information: Apparent size 1.2? arcmin. In the Large Magellanic Cloud.

NGC 1862 (= an OCL in the LMC)
Discovered (Jan 31, 1835) by John Herschel

Historical Identification: Per Dreyer, NGC 1862 (= GC 1072 = JH 2789, 1860 RA 05 12 06, NPD 156 18.8) is "pretty faint, large, irregularly round, very gradually brighter middle, mottled but not resolved".
Physical Information: Apparent size 0.3? arcmin. In the Large Magellanic Cloud.

NGC 1863 (= an OCL in the LMC)
Possibly observed (Sep 5, 1826) by James Dunlop
Discovered (Nov 3, 1834) by John Herschel
A magnitude 11.0 open cluster in Dorado (RA 05 11 39.6, Dec -68 43 37)

Historical Identification: Per Dreyer, NGC 1863 (= GC 1073 = JH 2791, Dunlop 173?, 1860 RA 05 12 19, NPD 158 53.4) is "very bright, very small, round, mottled but not resolved or stellar". (Steinicke states = Dunlop 173.)
Discovery Notes: Dunlop 173? in Dreyer's entry means that Herschel thought Dunlop 173 might be his (JH) 2791 and listed it as such (with a question mark) in the GC, and as a result so did Dreyer in the NGC. (Steinicke states = Dunlop 173.) means it is now thought certain that Dunlop 173 is NGC 1863.
Physical Information: Apparent size 0.5? arcmin. In the Large Magellanic Cloud.

NGC 1864 (= an OCL in the LMC)
Discovered (Dec 23, 1834) by John Herschel
A magnitude 12.9 open cluster in Dorado (RA 05 12 40.7, Dec -67 37 17)

Historical Identification: Per Dreyer, NGC 1864 (= GC 1074 = JH 2792, 1860 RA 05 12 56, NPD 157 47.3) is "faint, pretty small, irregularly round, brighter middle, mottled but not resolved or stellar".
Physical Information: Apparent size 0.9? arcmin. In the Large Magellanic Cloud.

NGC 1865 (= an OCL in the LMC)
Almost certainly not observed (Sep 25, 1826) by James Dunlop
Discovered (Dec 24, 1834) by John Herschel
A magnitude 12.9 open cluster in Dorado (RA 05 12 25.1, Dec -68 46 16)

Historical Identification: Per Dreyer, NGC 1865 (= GC 1075 = JH 2794, Dunlop 173??, 1860 RA 05 13 06, NPD 158 55.6) is "very faint, pretty large, round, very gradually a little brighter middle". (Steinicke now assigns Dunlop 173 to NGC 1863.)
Discovery Notes: Dunlop 173?? in Dreyer's entry means that Herschel thought there was a remote possibility that Dunlop 173 might be his (JH) 2794 and listed it as such (with a double question mark) in the GC, and as a result so did Dreyer in the NGC. (Steinicke now assigns Dunlop 173 to NGC 1863.) means it is now thought certain that Dunlop 173 is not NGC 1865.
Physical Information: Apparent size 0.8? arcmin. In the Large Magellanic Cloud.

NGC 1866 (= an OCL in the LMC)
Discovered (Aug 3, 1826) by James Dunlop
Discovered (Nov 23, 1834) by John Herschel
A magnitude 9.7 open cluster in Dorado (RA 05 13 39.1, Dec -65 27 56)

Historical Identification: Per Dreyer, NGC 1866 (= GC 1076 = JH 2793, Dunlop 247? 248?, 1860 RA 05 13 11, NPD 155 37.6) is "very bright, large, round, very gradually much brighter middle, mottled but not resolved". (Steinicke has a similar identification with Dunlop 247 and/or 248, but without the question marks.)
Discovery Notes: Dunlop 247? 248? in Dreyer's entry means that Herschel thought Dunlop 247 and/or 248 might be his (JH) 2793 and listed it as such (with question marks) in the GC, and as a result so did Dreyer in the NGC. (Steinicke has a similar identification with Dunlop 247 and/or 248, but without the question marks.) means it is now thought certain that Dunlop 247 and/or 248 is/are NGC 1866.
Physical Information: Apparent size 4.5? arcmin. In the Large Magellanic Cloud.

NGC 1867 (= an OCL in the LMC)
Discovered (Jan 3, 1837) by John Herschel

Historical Identification: Per Dreyer, NGC 1867 (= GC 1077 = JH 2795, 1860 RA 05 13 27, NPD 156 27.1) is "extremely faint, pretty large, round".
Physical Information: Apparent size 1.3? arcmin. In the Large Magellanic Cloud.

NGC 1868 (= an OCL in the LMC)
Discovered (Nov 30, 1834) by John Herschel
A magnitude 11.6 open cluster in Dorado (RA 05 14 36.5, Dec -63 57 18)

Historical Identification: Per Dreyer, NGC 1868 (= GC 1078 = JH 2796, 1860 RA 05 13 42, NPD 154 06.6) is "pretty bright, pretty large, round, very gradually a little brighter middle".
Physical Information: Apparent size 3.9? arcmin. In the Large Magellanic Cloud.

NGC 1869 (= an OCL and EN in the LMC)
Discovered (Sep 24, 1826) by James Dunlop
Discovered (Dec 20, 1835) by John Herschel
An open cluster and emission nebula in Dorado (RA 05 13 52.0, Dec -67 22 40)

Historical Identification: Per Dreyer, NGC 1869 (= GC 1079 = JH 2798, Dunlop 210, 1860 RA 05 13 58, NPD 157 32.1) is a "cluster, large, pretty rich, scattered stars".
Discovery Notes: Dunlop 210 in Dreyer's entry means that Herschel thought Dunlop 210 was his (JH) 2798 and listed it as such in the GC, and as a result so did Dreyer in the NGC. The lack of any other comment means that the identification is still thought to be correct. However, as indicated by the entries at NGC 1871 and 1873, it is now thought that Dunlop 210 referred to all three NGC objects.
Physical Information: Apparent size 14? arcmin. In the Large Magellanic Cloud. Part of a triple "association" with NGC 1871 and 1873.

NGC 1870 (= an OCL in the LMC)
Discovered (Aug 3, 1826) by James Dunlop
Discovered (Nov 24, 1834) by John Herschel
A magnitude 11.3 open cluster in Dorado (RA 05 13 10.0, Dec -69 07 01)

Historical Identification: Per Dreyer, NGC 1870 (= GC 1080 = JH 2799, (Dunlop 123), 1860 RA 05 13 59, NPD 159 16.5) is "bright, small, round, gradually a little brighter middle".
Discovery Notes: (Dunlop 123) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1870 is probably the object recorded as Dunlop 123.
Physical Information: Apparent size 0.5? arcmin. In the Large Magellanic Cloud.

NGC 1871 (= an OCL and EN in the LMC)
Discovered (Sep 5, 1826) by James Dunlop
Discovered (Nov 2, 1834) by John Herschel
A magnitude 10.1 open cluster and emission nebula in Dorado (RA 05 13 51.8, Dec -67 27 10)

Historical Identification: Per Dreyer, NGC 1871 (= GC 1081 = JH 2800, (Dunlop 210), 1860 RA 05 14 06, NPD 157 36.8) is a "cluster, a little rich, 2nd of several", the others being NGC 1869 and 1873.
Discovery Notes: (Dunlop 210) indicates that Herschel was unable to tell whether any of Dunlop's objects corresponded to (JH) 2800, did not include any reference to any of them in the entry for GC 1081, and as a result, neither did Dreyer in the entry for NGC 1871; but it is now thought that Dunlop 210 referred to the triple listed as NGC NGC 1869, 1871 and 1873.
Physical Information: Apparent size 2.0? arcmin. In the Large Magellanic Cloud. Part of a triple "association" with NGC 1869 and 1873.

NGC 1872 (= an OCL in the LMC)
Discovered (Sep 24, 1826) by James Dunlop
Discovered (Nov 3, 1834) by John Herschel
A magnitude 11.0 open cluster in Dorado (RA 05 13 10.8, Dec -69 19 02)

Historical Identification: Per Dreyer, NGC 1872 (= GC 1082 = JH 2802, (Dunlop 121), 1860 RA 05 14 08, NPD 159 28.2) is "pretty bright, round, gradually brighter middle, 1st of group", the others being NGC 1876, 1877 and 1880.
Discovery Notes: (Dunlop 121) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that NGC 1872 is probably the object recorded as Dunlop 121.
Physical Information: Apparent size 1.0? arcmin. In the Large Magellanic Cloud.

NGC 1873 (= an OCL and EN in the LMC)
Discovered (Sep 24, 1826) by James Dunlop
Discovered (Jan 2, 1837) by John Herschel
A magnitude 10.4 open cluster and emission nebula in Dorado (RA 05 13 55.7, Dec -67 20 04)

Historical Identification: Per Dreyer, NGC 1873 (= GC 1083 = JH 2801, (Dunlop 210), 1860 RA 05 14 09, NPD 157 29.4) is a "cluster, 3rd of several", the others being NGC 1869 and 1871.
Discovery Notes: (Dunlop 210) indicates that Herschel was unable to tell whether any of Dunlop's objects corresponded to (JH) 2801, did not include any reference to any of them in the entry for GC 1083, and as a result, neither did Dreyer in the entry for NGC 1873; but it is now thought that Dunlop 210 referred to the triple listed as NGC NGC 1869, 1871 and 1873.
Physical Information: Apparent size 3.5? arcmin. In the Large Magellanic Cloud. Part of a triple "association" with NGC 1869 and 1871.

Discovered (Dec 16, 1835) by John Herschel
A magnitude (9?) open cluster and emission nebula in Dorado (RA 05 13 11.7, Dec -69 22 35)

Historical Identification: Per Dreyer, NGC 1874 (= GC 1084 = JH 2803, (Dunlop 122), 1860 RA 05 14 10, NPD 159 31.9) is a "nebula and cluster, binuclear".
Discovery Notes: (Dunlop 122) indicates that Herschel was unable to identify Dunlop's object, did not include it in the GC, and as a result, neither did Dreyer in the NGC; but it is now thought that Dunlop 122 corresponds to NGC 1874, 1876, 1877 and 1880.
