NGC 6150 (= PGC 58105)
Discovered (Mar 18, 1787) by William Herschel
Also observed (date?) by John Herschel
A 14th-magnitude elliptical galaxy (type E5??) in Hercules (RA 16 25 49.9, Dec +40 29 20)
Historical Identification: Per Dreyer, NGC 6150 (= GC 4198 = JH 1959 = WH III 639, 1860 RA 16 21 10, NPD 49 13.0) is "very faint, very small, round".
Physical Information: Based on a recessional velocity of 8720 km/sec, NGC 6150 is about 405 million light years away. (Need to apply relativistic correction to Hubble distance.) Given that and its apparent size of 1.3 by 0.65? arcmin, it is about 150 thousand light years across.

PGC 58100 (= "NGC 6150B")
Not an NGC object but listed here since sometimes called NGC 6150B
A 14th-magnitude spiral galaxy (type Sab?) in Hercules (RA 16 25 44.4, Dec +40 28 32)
Physical Information: Based on a recessional velocity of 9535 km/sec, PGC 58100 is about 445 million light years away. (Need to apply relativistic correction to Hubble distance.) Given that and its apparent size of 0.7 by 0.3 arcmin, it is about 90 thousand light years across. Although peculiar (non-Hubble expansion) velocities could be responsible for the difference in recessional velocity between PGC 58100 and NGC 6150 (which see for images of the pair), their lack of any obvious gravitational interaction suggests that the smaller galaxy truly is a background object, and not physically related to its apparent companion.

NGC 6187 (= PGC 58429)
Discovered (Oct 5, 1883) by Charles Young
A 14th-magnitude spiral galaxy (type S??) in Draco (RA 16 31 36.6, Dec +57 42 26)
Historical Identification: Per Dreyer, NGC 6187 (Young, 1860 RA 16 28 58, NPD 31 59.3) is "very faint, very small, a little brighter middle".
Physical Information: Apparent size 0.4 by 0.3? arcmin.
NGC 6188
Discovered (Apr 15, 1836) by John Herschel
An emission and reflection nebula in Ara (RA 16 40 05.0, Dec -48 39 42)
Historical Identification: Per Dreyer, NGC 6188 (= GC 4223 = JH 3640, 1860 RA 16 29 15, NPD 138 44) is "a remarkable object, faint, very large, very irregularly extended, bright star involved".
Physical Information: NGC 6188 is a 20 by 12 arcmin wide emission and reflection nebula to the west (to the right in the images below) of a very young association of stars ( NGC 6193) that is heating and lighting up the eastern (left) side of the nebula. The nebula and cluster are about 4000 light years away, so the half-degree wide images below cover a region about 35 light years across. As can be seen in these wide-field views of NGC 6188 and 6193, most of the clouds of gas and dust in the region are relatively cool and dark. The region being fiercely heated and sculpted by the radiation from the nearby cluster of stars is also referred to as RCW 108.

NGC 6192 (= OCL 988)

A 9th-magnitude open cluster (type I2p) in Scorpius (RA 16 40 20.8, Dec -43 21 55)
Historical Identification: Per Dreyer, NGC 6192 (= GC 4224 = JH 3641, Dunlop 483, 1860 RA 16 30 29, NPD 133 05.3) is "a cluster, pretty large, pretty rich, irregularly round, stars from 11th to 14th magnitude".

NGC 6193
(= OCL 975 = C82 = "PGC 3518670" = ESO 226-SC020)
Discovered (May 14, 1826) by James Dunlop
Also observed (date?) by John Herschel
A 5th-magnitude open cluster (type II3p) in Ara (RA 16 41 20.3, Dec -48 45 48)
Historical Identification: Per Dreyer, NGC 6193 (= GC 4225 = JH 3642, Dunlop 413, 1860 RA 16 30 52, NPD 138 29.1) is "a cluster, very large, a little rich, a little compressed, well resolved, clearly consisting of stars, faint nebula involved".
PGC Designation Note: As usual for NGC objects, HyperLEDA assigned a PGC designation to this object, even though it isn't a galaxy; but as also usual in such situations, a search of the database for that designation returns no result, hence its being in quotes.
Physical Information: NGC 6193 is an OB1 association (a group of extremely young stars, at most a few million years old, which therefore includes some extremely hot, bright stars) that is heating and lighting up the gas and dust surrounding it, especially the emission and reflection nebula to the west (to the right in the images below) which is listed as NGC 6188. Most of the radiation heating, sculpting, and compressing the nearby clouds of gas and dust comes from the bright object near the center of the cluster, which is actually a binary star consisting of two extremely massive, extremely bright O-type stars. The cluster and nebula lie about 4000 light years away, so the 12 arcmin image below covers a region about 14 light years across, and the 30 arcmin image covers a region about 35 light years across. As can be seen in the wide-field views of NGC 6193 and 6188, most of the clouds of gas and dust in the region are relatively cool and dark. The region being fiercely heated and sculpted by the radiation from the nearby cluster of stars is also referred to as RCW 108.
