NGC 2667 (= IC 2410 = PGC 24741)
Discovered (Feb 18, 1862) by Heinrich d'Arrest (and later listed as NGC 2667)
Discovered (Jan 13, 1901) by Max Wolf (and later listed as IC 2410)
A magnitude 14.0 spiral galaxy (type S?) in Cancer (RA 08 48 27.2, Dec +19 01 10)
Historical Identification: Per Dreyer, NGC 2667 (= GC 1699, d'Arrest, 1860 RA 08 40 21, NPD 70 27.8) is "extremely faint". The position precesses to RA 08 48 20.6, Dec +19 01 27, which is almost 7sW and 16"N of the presumably correct position. There are two faint spirals located just to the east of Dreyer's position, but the brighter one is almost certainly the correct one, for if d'Arrest had been able to see the fainter, he should have seen both; so the identity is reasonably certain. Both objects were photographed by Wolf, with the brighter one becoming IC 2410, thanks to the error in d'Arrest's position, and the fainter, previously unobserved galaxy becoming IC 2411.

IC 2411 (= "NGC 2667B" = PGC 24755)
A magnitude 14.7 spiral galaxy (type S?) in Cancer (RA 08 48 30.2, Dec +19 02 38)
Warning About Non-Standard Designations: PGC 24755 is the fainter of the two galaxies noted at NGC 2667, and due to its proximity to that galaxy, sometimes called NGC 2667B. However, it has a perfectly good IC listing, so that is its proper designation, and this entry only notes the erroneous use of the NGC number. Therefore, see NGC 2667 for a wide-field image, and IC 2411 for anything else. (Warning: Wikisky shows both galaxies as NGC 2667.)
NGC 2668 (= PGC 24791)

(Corwin gives two positions for the cluster, the other being RA 08 44 37.0, Dec -53 54 06)
Historical Identification: Per Dreyer, NGC 2669 (= GC 1701 = JH 3140, Sûfi, 1860 RA 08 40 51, NPD 143 27.5) is "a cluster, large, poor, a little compressed, stars from 10th to 13th magnitude".
Discovery Note: The observational credit assigned to Al-Sufi is by Dreyer, as it is not noted in the GC, and presumably based on Al-Sufi's "Book of Fixed Stars", published in 964 CE.

A magnitude 13.5 elliptical galaxy (type E0) in Cancer (RA 08 49 24.2, Dec +19 04 28)
Historical Identification: Per Dreyer, NGC 2673 (= GC 1705, 3rd Lord Rosse, 1860 RA 08 41 25, NPD 70 24.9) is "very faint, very small, close east of h 526", (JH) 526 being NGC 2672.
Discovery Notes: Although Dreyer credits the discovery to William Parsons, 3rd Earl of Rosse, he notes that many of Rosse's nebular discoveries were actually made by one of his assistants, in this case George Stoney. (The attribution to William Herschel (as WH II 48 = WH II 80) and John Herschel (as JH 526) is by Steinicke; this will be explored further in the next iteration of this page.)

Discovered (Mar 17, 1831) by John Herschel
A magnitude 14.6 lenticular galaxy (type SB0?) in Cancer (RA 08 50 01.3, Dec +19 00 35)
Historical Identification: Per Dreyer, NGC 2677 (= GC 1707 = JH 527 = WH II 48?, 1860 RA 08 42 01, NPD 70 28.3) is "extremely faint, very small, partially resolved (some stars seen), (very small cluster)".
Discovery Note: Since Dreyer (and/or John Herschel) lists WH II 48 as equal to WH II 80 = NGC 2672, the presumption would be that William Herschel did not observe NGC 2677; but since the possibility is noted in the NGC, it is also shown above, albeit with a caveat. I will do some research on this in the next iteration of this page, and try to resolve the question. (Unlike NGC 2672 & 2673, Steinicke does NOT list William Herschel as an observer of NGC 2677.)

A magnitude 12.6 lenticular galaxy (type (R)SB0(r)a) in Cancer (RA 08 51 32.9, Dec +30 51 55)
Historical Identification: Per Dreyer, NGC 2679 (= GC 1709 = JH 529 = WH III 294, 1860 RA 08 42 59, NPD 58 36.6) is "pretty faint, pretty small, round, brighter middle, a double nebula with NGC 2680".
Physical Information:
Apparent size 1.6 by 1.3 arcmin. "Involved" with NGC 2680, which see.

NGC 2680
Recorded (Feb 26, 1851) by Bindon Stoney
A magnitude 14.5 pair of stars in Cancer (RA 08 51 33.7, Dec +30 51 57)
Historical Identification: Per Dreyer, NGC 2680 (= GC 1710, 3rd Lord Rosse, 1860 RA 08 43 00, NPD 58 36.6) is "very faint, very small, round, brighter middle, a double nebula with NGC 2679". The position is identical to that of NGC 2679, save for being a second of right ascension to the east; and on lower quality images there is a somewhat fuzzy looking object just to the east of the nucleus of the larger galaxy. As a result, NGC 2680 is listed in most databases as a 15th-magnitude compact galaxy of apparent size 0.2 by 0.15 arcmin, superimposed on or part of a physical pair with NGC 2679. However, in higher quality images it is obvious that it is merely the two stars immediately to the east of NGC 2679's nucleus. (Note: The color and contrast of the higher quality image have been adjusted to ensure that the sharpness of the image is not compromised, while emphasizing the different appearance of the stars compared to their nebular "companion".)
Discovery Notes: Although Dreyer credits the discovery to William Parsons, 3rd Earl of Rosse, he notes that many of Rosse's nebular discoveries were actually made by one of his assistants, in this case Bindon Stoney.

Also observed (Feb 16, 1831) by John Herschel
A magnitude 10.3 lenticular galaxy (type (R)SAB(rs)0/a) in Ursa Major (RA 08 53 32.7, Dec +51 18 49)
Historical Identification: Per Dreyer, NGC 2681 (= GC 1711 = JH 530 = WH I 242, 1860 RA 08 43 28, NPD 38 09.8) is "very bright, very large, very gradaully then very suddenly much brighter middle equal to 10th magnitude star".
Physical Information: NGC 2681 is used by the de Vaucouleurs atlas of galaxy types as an example of type (R)SAB(rs)0/a.

NGC 2682 (= M67 = OCL 549)
Not observed (1779) by Barnaba Oriani
Discovered (1779) by Johann Koehler
Recorded (April 6, 1780) by Charles Messier
Also observed (Mar 3, 1826) by John Herschel
A magnitude 6.9 open cluster (type II2m) in Cancer (RA 08 51 20.0, Dec +11 49 30)
Historical Identification: Per Dreyer, NGC 2682 (= GC 1712 = JH 531, M67, Oriani, 1860 RA 08 43 34, NPD 77 40.6) is "a remarkble object, a cluster, very bright, very large, extremely rich, a little compressed, stars from 10th to 15th magnitude".
Discovery Note: Per Steinicke, this is one of eleven Messier objects for which Dreyer assigned the wrong discoverer. Although Oriani did observe three Messier objects while observing the comet of 1779 (and as a result was the discoverer of M61), he never observed M67.
Physical Information: From NOAO site: M67 is an open star cluster in the constellation Cancer. One of the oldest known such clusters, M67 is believed to be 10 billion years old. It contains approximately 500 stars within its 12 light-year diameter and is located some 2500 light-years away.

NGC 2683 (= PGC 24930)
Discovered (Feb 5, 1788) by William Herschel
Also observed (Mar 5, 1828) by John Herschel
A magnitude 9.8 spiral galaxy (type SA(rs)b) in Lynx (RA 08 52 41.3, Dec +33 25 19)
Historical Identification: Per Dreyer, NGC 2683 (= GC 1713 = JH 532 = WH I 200, 1860 RA 08 43 59, NPD 56 03.4) is "very bright, very large, very much extended 39°, gradually much brighter middle".
Physical Information: NGC 2683's recessional velocity of 410 km/sec is too small to yield a reliable estimate of distance, as its peculiar (non-Hubble-expansion) velocity could be a significant part of its overall motion. Ignoring that caveat, its redshift implies a distance of 18 million light years, in reasonable agreement with redshift-independent distance estimates of 18 to 45 million light years. Given its 9.3 by 2.2 arcmin apparent size, the galaxy is about 50 thousand light years across if at the closer distance, and over 100 thousand light years across if the more distant estimate is closer to being correct. (The galaxy's impressive appearance and well-organized structure suggest that the larger size and distance are more likely, but appearances are often misleading.) A study of irregularities in the velocity distribution of stars in the central region suggests that like our own galaxy, NGC 2683 has a barred structure; but because of the galaxy's nearly edge-on presentation, it is impossible to tell that from the images shown here. The HST closeup (third below) shows the relatively bright core (the reason it is classified as a Seyfert (type Sy 2) galaxy), extensive dust clouds outlined by the light of stars scattered throughout its disk, and numerous clusters of hot young blue stars scattered along the spiral arms which are mostly shrouded by the clouds of gas and dust lying in the plane of its galactic equator.

2MASXJ08524947+3321216 (= "0853+3321", above)
Not an NGC object but listed here because of its interesting characteristics
A 17th-(B)magnitude galaxy (type ?) in Lynx (RA 08 52 49.6, Dec +33 21 21)
Physical Information: This catalog mostly ignores galaxies that do not have an NGC, IC or PGC entry; but in searching for such an identification of 2MASXJ08524947+3321216, information was obtained which seems of adequate interest to justify an entry, despite its not being included in any of those catalogs. Given its recessional velocity of 33600 km/sec, a straightforward calculation indicates that the galaxy is about 1.5 billion light years away. However, for such distant objects, we must take into account the expansion of the Universe during the billion and a half years it took the light by which we see the object to reach us. Doing that indicates that we see the galaxy when it was about 1.375 billion light years away, and that it took the light it emitted at that time about 1.45 billion years to reach us (the difference between the two numbers being due to the expansion of the space through which the light passed on its way here). Given that and the galaxy's apparent size of about 0.25 by 0.2 arcmin, it is about 100 thousand light years across. In other words, this faint speck is about what our galaxy would look like if seen by the inhabitants of worlds in that distant object.

Also observed (Mar 7, 1831) by John Herschel
A magnitude 12.9 spiral galaxy (type Sc) in Ursa Major (RA 08 54 54.0, Dec +49 09 38)
Historical Identification: Per Dreyer, NGC 2684 (= GC 1714 = JH 533 = WH III 712, 1860 RA 08 45 02, NPD 40 18.6) is "faint, pretty large, round, gradually brighter middle, 4 small (faint) stars near".

NGC 2686 (= PGC 25025 + PGC 25026)
Discovered (Mar 11, 1858) by R. J. Mitchell
A pair of galaxies in Ursa Major
PGC 25026 = A magnitude 14.8 lenticular galaxy (type E/S0?) at RA 08 54 58.9, Dec +49 08 32
PGC 25025 = A magnitude 16.2 lenticular galaxy (type SB0?) at RA 08 55 00.6, Dec +49 08 33
Historical Identification: Per Dreyer, NGC 2686 (= GC 1715, 3rd Lord Rosse, 1860 RA 08 45, NPD 40 20±) is "very faint, very small, double or single star close to east". Although Mitchell's description suggests that the eastern member of the pair might not be part of the nebula, his diagram clearly shows the object as double, so both galaxies must be considered part of the NGC object.
Discovery Notes: Although Dreyer credits the discovery to William Parsons, 3rd Earl of Rosse, he notes that many of Rosse's nebular discoveries were actually made by one of his assistants, in this case R. J. Mitchell.
Physical Information:
Apparent size of PGC 25025 = 0.3 by 0.2 arcmin; of PGC 25026 = 0.5 by 0.3 arcmin

NGC 2687 (= PGC 25030 (+ PGC 25031?))
Discovered (Mar 11, 1858) by R. J. Mitchell
A magnitude 15.7 spiral galaxy (type Sa?) in Ursa Major (RA 08 55 06.0, Dec +49 09 22)
(and perhaps a magnitude 17.1 galaxy (type S0/a? or Sab?) at RA 08 55 05.0, Dec +49 09 23)
Historical Identification: Per Dreyer, NGC 2687 (= GC 1716, 3rd Lord Rosse, 1860 RA 08 45, NPD 40 19±) is "very small". The very rough position precesses to RA 08 54 51.4, Dec +49 09 25, on the southwestern rim of NGC 2684, which is such a poor position that it could make it difficult or impossible to tell which of the numerous galaxies in the area is NGC 2687. However, Mitchell's diagram clearly shows the various nebulae in the region, so there is no doubt that the galaxy (or pair of galaxies) listed above is/are the NGC object.
Note About PGC 25031's Inclusion In NGC 2687: Although PGC 25031 is often treated as part of the NGC object, Mitchell's diagram shows only a single object and his notes do nothing to alter that impression; and PGC 25031 is so faint that it probably did not influence his observation of its brighter companion, and should probably not be considered part of the NGC object. However, since every database I've checked lists the two objects by the non-standard designations of NGC 2687A and 2687B (and worse yet, assigns "B" to the brighter object which certainly is part of the NGC object), this entry (reluctantly) treats both galaxies as part of NGC 2687.
Discovery Notes: Although Dreyer credits the discovery to William Parsons, 3rd Earl of Rosse, he notes that many of Rosse's nebular discoveries were actually made by one of his assistants, in this case R. J. Mitchell.
Physical Information: PGC 25030: Vr 14720 km/sec, z 0.049101, Apparent size 0.3 by 0.2 arcmin?
Nothing appears to be known about PGC 25031 save for its apparent size; most likely, the inclusion of it as a part of NGC 2687 has led to the assumption that it is a physical companion of the brighter galaxy, and a lack of interest in verifying or disproving that supposition. I can't even find any effort to determine its type, and given the relatively low quality of the best images available, any opinion about the accuracy of the estimates I've given is left up to the reader.

A magnitude 15.8 spiral galaxy (type SB(rs)b?) in Ursa Major (RA 08 55 11.6, Dec +49 07 21)
Historical Identification: Per Dreyer, NGC 2688 (= GC 1717, 3rd Lord Rosse, 1860 RA 08 45, NPD 40 21±) is "very very faint, small". Clearly shown on Mitchell's diagram of the region.

NGC 2689 (= PGC 2333935)

A magnitude 16.3 lenticular galaxy (type S0/a?) in Ursa Major (RA 08 55 25.4, Dec +49 06 56)
Historical Identification: Per Dreyer, NGC 2689 (3rd Lord Rosse, 1860 RA 08 45, NPD 40 22±) is "very very faint, small". Note: PGC 25042 is sometimes misidentified as NGC 2689, but Mitchell's diagram clearly shows that the nebula is in a southeastern line with NGC 2686 and 2688, and must be the galaxy listed above.

Historical Misidentification: As noted above, this object is sometimes misidentified as NGC 2689 (e.g., NED incorrectly treats PGC 25042 and PGC 2333935 (= NGC 2689) as the same object); but as the discussion of that NGC object shows, that cannot be correct.
