NGC 4452 (= PGC 41060)
Discovered (Mar 15, 1784) by William Herschel
A 12th-magnitude lenticular galaxy (type S0) in Virgo (RA 12 28 43.3, Dec +11 45 18)
Listed as a member (VCC 1125) of the Virgo Cluster. The disk of NGC 4452 looks unusually thin because we see it exactly edge-on. Most spirals have relatively thin disks, but we see them at an angle, making the disk appear thicker. One unusual aspect of NGC 4452 is that its disk has relatively little dust, so its stellar contents are not obscured by dust lanes. In addition, it has a very small central bulge, or nucleus. The nucleus is usually much thicker than the disk, but in this case it barely pokes above or below the plane of the disk. The negligible bulge of its nucleus and the lack of any dust lanes suggests that NGC 4452 might not exhibit a spiral structure even if seen from above (since such structures are outlined by the light of hot young stars recently formed from clouds of gas and dust within the spiral arms). NGC 4425's recessional velocity of 165 km/sec is too small in comparison to peculiar (non-Hubble expansion) velocities to estimate its distance; but redshift-independent distance estimates place it about 50 to 55 million light years away, on the near side of the Virgo Cluster of galaxies, the nearest large cluster to us. Given that and its apparent size of 2.55 by 0.8 arcmin, it is about 40 thousand light years across.

An 11th-magnitude lenticular galaxy (type SB0+(s)?) in Virgo (RA 12 29 03.0, Dec +13 11 02)

The position precesses to RA 12 29 03.3, Dec +13 11 01, right on the galaxy, so the identification is certain. (See NGC 4443 for a discussion of the double listing.)

Discovered (Mar 31, 1886) by Guillaume Bigourdan
A 15th-magnitude spiral galaxy (type Sc?) in Virgo (RA 12 29 23.6, Dec +08 01 33)
Per Dreyer, NGC 4465 (Bigourdan (list II #54), 1860 RA 12 22 19, NPD 81 12) is "very faint, very diffuse". The second IC adds "Not found on plate by Schwassmann". The position precesses to RA 12 29 26.2, Dec +08 01 31, only half an arcmin east of the galaxy, so the identification is certain, and Schwassmann's inability to find the object was probably due to its faintness and small size (and perhaps to its proximity to the much larger and brighter M49). Apparent size 0.5 by 0.3 arcmin. Listed as a member (VCC 1182) of the Virgo Cluster, but actually a much more distant background galaxy.

Discovered (Apr 28, 1851) by Otto Struve
A 14th-magnitude elliptical galaxy (type E2) in Virgo (RA 12 29 30.2, Dec +07 59 34)
Per Dreyer, NGC 4467 (Otto Struve, d'Arrest, 1860 RA 12 22 24, NPD 81 13.6) is "very faint, very small, a little extended". The second IC adds "Not found on plate by Schwassmann". The position precesses to RA 12 29 31.2, Dec +07 59 55, less than half an arcmin northeast of the galaxy, so the identification is certain, and Schwassmann's inability to find the object was probably due to its faintness and small size (and perhaps to its proximity to the much larger and brighter M49). Apparent size 0.4 by 0.3 arcmin. Listed as a member (VCC 1192) of the Virgo Cluster.

NGC 4471
Recorded (Jul 29, 1861) by Julius Schmidt
A 15th-magnitude star in Virgo (RA 12 29 42.0, Dec +07 53 45)
or a 15th-magnitude star at RA 12 29 40.6, Dec +07 54 40
or (but very unlikely?) a galaxy (PGC 41185) at RA 12 29 37.1, Dec +07 55 58 (see next entry)
Per Dreyer, NGC 4471 (GC 5655, J. Schmidt, 1860 RA 12 22 34, NPD 81 19.4) is "very faint, very small (not found by d'Arrest". The position precesses to RA 12 29 41.2, Dec +07 54 08, not quite midway between the 15th-magnitude stars listed above, but there appears to be no way to tell which is what Schmidt meant to record. There is also a 15th-magnitude galaxy ( PGC 41185, which see) to the northwest of the stars that is sometimes identified as NGC 4471, but per Corwin that is almost certainly too faint for Schmidt to have seen (in visual observations stars look much brighter than "equal-brightness" nebulae, since all their light is concentrated in a single point). So odds are that NGC 4471 was one of the stars, even if there is no way to tell which one.

PGC 41185 (not = NGC 4471)
Probably not an NGC object but listed here since sometimes (mis?)identified as NGC 4471
A 15th-magnitude elliptical galaxy (type E1?) in Virgo (RA 12 29 37.1, Dec +07 55 58)
As noted in the entry for NGC 4471, PGC 41185 is often misidentified as that NGC object, even though it is almost certainly too faint for Schmidt to have observed, since nebular objects look much fainter than stars to visual observers as a result of their light being spread over a larger area. Apparent size 0.45 by 0.4 arcmin. Listed as a member (VCC 1203) of the Virgo Cluster.
Above, a 2.4 arcmin wide closeup of PGC 41185 (for a wide-field view see NGC 4471)
NGC 4472 (= PGC 41220 = M49 = Arp 134)
Discovered (Feb 19, 1771) by Charles Messier and listed as M49
Also observed (April 22, 1779) by Barnabas Oriani
Probably observed (Jan 23, 1783) by William Herschel
Also observed (May 9, 1828) by John Herschel
A magnitude 8.4 elliptical galaxy (type E2?) in Virgo (RA 12 29 46.8, Dec +08 00 02)
Historical Identification: Per Dreyer, NGC 4472 (= GC 3021 = JH 1294 (= WH I 7), Oriani, M49, 1860 RA 12 22 40, NPD 81 13.5) is "very bright, large, round, much brighter middle, mottled but not resolved". The position precesses to RA 12 29 47.1, Dec +08 00 02, essentially dead center on the galaxy listed above and the description fits, so the identification is certain.
Discovery Notes: Although discovered by Messier, M49 was also observed by Oriani while following the path of the Comet of 1779. In 1844, Admiral William Smyth's Bedford Catalogue conflated the two observations and listed the nebula as having been discovered by Oriani in 1771. This error was copied in John Herschel's GC, and since the New General Catalog was an expansion of the GC, was also repeated in the NGC (though in a sense also giving Messier credit for the discovery, since his appellation of M49 was also used). William Herschel's probable observation of 1783 was ignored by Dreyer in compiling the NGC because Herschel's position was uncertain, and he mistook the object he observed for M61; however, in a much later and very thorough analysis of all of Herschel's unpublished observations, Dreyer concluded that (WH) I 7 must be identical to M49, hence my addition of that observation (in parentheses) to Dreyer's listing for NGC 4472.
Physical Information: Apparent size 10.2 by 8.3 arcmin. Listed as a member (VCC 1226) of the Virgo Cluster. Used by the de Vaucouleurs Atlas of Galaxy Types as an example of galaxy type E +2. Used by the Arp Atlas as an example of an elliptical galaxy with nearby fragments.

A 13th-magnitude elliptical galaxy (type E4) in Virgo (RA 12 30 10.3, Dec +10 46 46)
Per Dreyer, NGC 4482 (GC 3033 = WH III 40, 1860 RA 12 23 33, NPD 78 29.0) is "extremely faint, pretty large". The second IC adds "Not found by Frost, but it has been observed by Bigourdan, at RA 12 23 04". (The 30 second error in Herschel's RA was also noted by Dreyer in his study of Herschel's papers.) The corrected position precesses to RA 12 30 10.0, Dec +10 44 32, about two arcmin due south of the galaxy, but there is nothing else nearby and the description seems perfect, so the identification is considered certain.

A 14th-magnitude spiral galaxy (type SA(s)c pec?) in Virgo (RA 12 28 52.7, Dec -11 39 08)
Per Dreyer, NGC 4484 (GC 3034 = JH 1300, 1860 RA 12 23 37, NPD 100 51.9) is "pretty faint, small, round, gradually brighter middle". The second IC adds "RA 2 minutes too great (per Howe). (h. only one observation)", "h." being shorthand for John Herschel. The corrected position precesses to RA 12 28 51.4, Dec -11 38 24, less than an arcmin north of the galaxy, and there is nothing else nearby, so the identification is considered certain. Apparent size 1.5 by 1.5 arcmin.

Also observed (Mar 10, 1826) by John Herschel
A magnitude 8.6 elliptical galaxy (type E1? peculiar) in Virgo (12 30 49.4, Dec +12 23 28)
Historical Identification: Per Dreyer, NGC 4486 (= GC 3035 = JH 1301, M87, 1860 RA 12 23 44, NPD 76 50.1) is "very bright, very large, round, much brighter middle, 3rd of 3", the others being NGC 4476 and 4478. The position precesses to RA 12 30 49.2, Dec +12 23 28, essentially dead center on the galaxy listed above and the description fits, so the identification is certain.
Physical Information: Apparent size 8.3 by 6.6? arcmin. Listed as a member (VCC 1316) of the Virgo Cluster. Used by the de Vaucouleurs Atlas of Galaxy Types as an example of galaxy type E +0-1. Used by the Arp Atlas as an example of a galaxy with a jet.

NGC 4492 (= PGC 41383 = IC 3438)
Discovered (Dec 28, 1785) by William Herschel (and later listed as NGC 4492)
Discovered (Jan 23, 1900) by Arnold Schwassmann (and later listed as IC 3438)
A 13th-magnitude spiral galaxy (type SA(s)a?) in Virgo (RA 12 30 59.7, Dec +08 04 41)
Per Dreyer, NGC 4492 (GC 3040 = JH 1305 = WH II 499, 1860 RA 12 23 53, NPD 81 08.9) is "pretty faint, pretty large, very gradually a little brighter middle, 2 stars near". The position precesses to RA 12 30 59.9, Dec +08 04 39, right on the galaxy, so the identification is certain (see IC 3438 for a discussion of the double listing.) Apparent size 2.7 by 2.6 arcmin. Listed as a member (VCC 1330) of the Virgo Cluster.

NGC 4493 (= PGC 41409)
Discovered (Mar 22, 1865) by Albert Marth
A 14th-magnitude elliptical galaxy (type E2) in Virgo (RA 12 31 08.4, Dec +00 36 49)
Per Dreyer, NGC 4493 (GC 5658 = Marth 241, 1860 RA 12 23 57, NPD 88 37) is "very faint, very small, irregularly round". The position precesses to RA 12 31 06.9, Dec +00 36 34, on the southwestern side of the galaxy, so the identification is certain. The only question is whether the fainter galaxy to the southeast ( PGC 1170468) should be considered part of the NGC object. Since the description is "irregularly round" the fainter galaxy might have affected Marth's observation, but the position is almost exactly on the brighter galaxy, and would presumably be between the two galaxies if the fainter one had a significant affect, so probably only the brighter galaxy should be considered part of NGC 4493. Apparent size 1.0 by 0.8 arcmin.

PGC 1170468
Not an NGC object but listed here due to its proximity to NGC 4493
A 16th-magnitude compact galaxy (type C) in Virgo (RA 12 31 11.0, Dec +00 36 22)
Apparent size 0.4 by 0.3 arcmin. As noted in the entry for NGC 4493 (which see for images), it is conceivable (though unlikely) that PGC 1170468 was part of what Marth observed, hence its placement here.
NGC 4494 (= PGC 41441)
Discovered (Apr 6, 1785) by William Herschel
A 10th-magnitude elliptical galaxy (type E1) in Coma Berenices (RA 12 31 24.0, Dec +25 46 30)

NGC 4496 (= PGC 41471, and probably = NGC 4505)
Discovered (Feb 23, 1784) by William Herschel (and later listed as NGC 4496)
Discovered (Mar 11, 1784) by William Herschel (and later listed as NGC 4505)
An 11th-magnitude irregular galaxy (type IB(rs)m pec?) in Virgo (RA 12 31 39.3, Dec +03 56 23)
Per Dreyer, NGC 4496 (GC 3045 = JH 1309 = WH II 36, 1860 RA 12 24 30, NPD 85 17.8) is "faint, considerably large, binuclear or a double nebula". The position precesses to RA 12 31 38.5, Dec +03 55 46, within the brighter member of what appears to be a double galaxy, so the identification is certain. Given the NGC description as a double galaxy, NGC 4496 should perhaps be considered equal to the pair of galaxies, but as it happens they are merely an optical double (having recessional velocities that differ by nearly 3000 km/sec), so the brighter northern galaxy is generally considered to be "the" NGC object, while being given both that appellation and NGC 4496A, and the fainter southern galaxy ( PGC 41473) is generally listed as "NGC 4496B". Per Corwin, the 3rd edition of the Reference Catalog of nearby galaxies (known as the RC3) lists three objects as NGC 4496, but as far as I can tell only the one listed here actually exists, so hopefully the reader won't run across any incorrect references to the others. Apparent size 3.9 by 3.1 arcmin. Listed as a member (VCC 1375) of the Virgo Cluster. (Note: NGC 4496 is listed as a spiral galaxy and its apparent companion as an irregular galaxy, but in the images below it looks like this is the reverse of their appearance; so the galaxy types listed here are based on that appearance, rather than existing references. Also, although their recessional velocities imply that they are at very different distances, redshift-independent distance estimates place them at the same distance, in which case they are an interacting pair, and both members of the Virgo Cluster. In other words, this pair needs to be restudied, to clear up the considerable confusion about its true nature.)

PGC 41473 (= "NGC 4496B")
Often called NGC 4496B due to proximity to NGC 4496
A 14th-magnitude spiral galaxy (type Sbc(rs)?) in Virgo (RA 12 31 40.9, Dec +03 55 35)
As noted in the entry for NGC 4496, PGC 41473 should perhaps be considered part of that NGC entry, but standard usage is to assign that only to its much brighter companion. Apparent size 0.8 by 0.6 arcmin. Listed as a member (VCC 1376) of the Virgo Cluster but actually much further away. Although an apparent companion of NGC 4496 (which see for images), their recessional velocities differ by nearly 3000 km/sec, so they are merely an optical double (but see the note at the end of the entry for NGC 4496).
