Per Dreyer, NGC 150 (= Swift list VI (#3), 1860 RA 00 26 50, NPD 118 35.1) is "pretty faint, pretty small, round". The second Index Catalog lists a corrected RA (per Howe and Delisle Stewart) of 00 27 19. Using the corrected RA and original NPD, the position precesses to RA 00 34 15.8, Dec -27 48 44, about 0.4 arcmin south of the center of the galaxy, but well within its outline, so the identification is certain. Based on the recessional velocity of 1585 km/sec, the galaxy is about 70 million light years away, in good agreement with redshift-independent distance estimates of 55 to 85 million light years. Given that and its apparent size of 3.9 by 1.9 arcmin, it is about 55 thousand light years across. NGC 150 is listed as a member of LGG 007, the NGC 134 group of galaxies, which includes NGC 115, 131 and 148, PGC 2000 (erroneously identified as IC 1554) and IC 1555, and PGC 2044. Several of these are also listed as members of a group of galaxies in (or near) Sculptor with recessional velocities of about 1500 to 1800 km/sec (this is not "the" Sculptor Group, a close neighbor to our Local Group, with an average recessional velocity of less than 300 km/sec); so all LGG 007 group members are presumably members of the larger group. (Note: Wikisky images of this galaxy are badly overexposed in the blue channel; so the views below are a composite of original DSS red-band images, which show greater detail, and the Wikisky DSS images.)

Per Dreyer, NGC 151 (= John Herschel's GC 74, 1860 RA 00 26 57, NPD 100 28.5) is "pretty faint, pretty large, slightly extended 90°, very gradually slightly brighter middle". (The identity with NGC 153 (which see for a discussion of the double listing) was published by Spitaler in time to be included in the first Index Catalog corrections.) Herschel's position precesses to RA 00 34 02.9, Dec -09 42 08, within 0.2 arcmin of the center of the galaxy, so the identification is certain. Based on the recessional velocity of 3745 km/sec, the galaxy is about 165 million light years away, in good agreement with redshift-independent distance estimates of 125 to 190 million light years. Given that and its apparent size of 2.6 by 1.1 arcmin, it is about 125 thousand light years across. NED lists it as a member of a group of galaxies, but does not specify which group; nor does the reference cited.

Per Dreyer, NGC 152 (= John Herschel's GC 75, 1860 RA 00 27 04, NPD 163 53.2) is "very faint, large, round, very gradually slightly brighter middle".

Per Dreyer, NGC 153 (= Swift's list IV (#1), 1860 RA 00 27 14, NPD 100 28.4) is "pretty faint, pretty small, round, star near to northeast". (The identity with NGC 151 was published by Spitaler in time to be included in the first Index Catalog corrections.) (Corwin has lengthy note about the identity)

Per Dreyer, NGC 154 (= John Herschel's GC 76, 1860 RA 00 27 14, NPD 103 26.0) is "extremely faint, very small, round".

Per Dreyer, NGC 155 (= Swift's list IV (#2), 1860 RA 00 27 24, NPD 101 31.7) is "pretty faint, small, round". The second Index Catalog lists a corrected RA (per Bigourdan) of 00 27 35.

Per Dreyer, NGC 156 (= Tempel's list V, 1860 RA 00 27 28, NPD 99 07) is "very small, northwest of II 3". (II 3 refers to object #3 in William Herschel's list II, which is NGC 157.) (Corwin has short note about NGC 156)

Per Dreyer, NGC 157 (= John Herschel's GC 78, 1860 RA 00 27 40, NPD 99 10.2) is "pretty bright, large, extended, between 2 considerably bright stars". (Corwin has brief note, but may not be relevant) Based on recessional velocity of 1650 km/sec, about 75 million light years away, in good agreement with redshift-independent distance estimates of 40 to 95 million light years. Given that and apparent size of 4.2 by 2.7 arcmins, about 90 thousand light years in diameter.

Per Dreyer, NGC 158 (= Tempel's list V, 1860 RA 00 27 51, NPD 99 05) is "very small, northeast of II 3". (II 3 refers to object #3 in William Herschel's list II, which is NGC 157.) (Corwin has note about object)

Per Dreyer, NGC 159 (= John Herschel's GC 77, 1860 RA 00 28 03, NPD 146 33.4) is "very faint, pretty small, round, gradually slightly brighter middle, 3 stars to east".

Per Dreyer, NGC 160 (= John Herschel's GC 79, 1860 RA 00 28 42, NPD 66 48.8) is "very faint, very small, stellar, 8th magnitude star 4 arcmin away 17° east of north". (The star is 7th-magnitude HD 3293.)

Per Dreyer, NGC 161 (= Swift's list VI (#4), 1860 RA 00 28 44, NPD 93 36.2) is "extremely faint, extremely small, round, nearly between 2 stars". The second Index Catalog lists a corrected RA (per Bigourdan) of 00 28 26.

Per Dreyer, NGC 162 (= Schultz, 1860 RA 00 28 48, NPD 66 48.4) is "extremely faint, stellar, h39 to southwest". The reference to h39 (= NGC 192) appears to be a typographical error, as that galaxy is in a different part of the sky. As it happens, Dreyer's notes for NGC 160 confirm the error, stating that Schultz was the first to see a nebula 78° east of north, 1.2 arcmin from h32 (= NGC 160), which means that galaxy must be the one near NGC 162. The position precesses to RA 00 36 09.8, Dec +23 57 55, within 0.3 arcmin of the star, and NGC 160 is in the correct relative position; so the identification with the star is certain. The attribution to d'Arrest involves a complicated story, not otherwise discussed online: Corwin and Steinicke's web pages attribute the discovery to Schultz, and although Steinicke's downloadable database lists d'Arrest as the discoverer, there is no explanation of the listing. However, Steinicke's book contains a two-page discussion of the problems Dreyer faced when dealing with identifications of nebulae by various observers in the region near NGC 160 and 169, which led Dreyer to (often incorrectly) assume that observations of one object were actually observations of another. The lengthy process of sorting out who saw what and when they saw it leads to the conclusion that Schultz was actually the third person to observe the star listed as NGC 162, and d'Arrest was the first. As an ironic end to this tale of mistakes and misinterpretations, it should be noted that (as in all too many cases) a Wikisky search for NGC 162 shows the wrong object, namely the galaxy PGC 2148 (= PGC 2156). For (correctly labeled) images of the region near NGC 162, see NGC 160.

Per Dreyer, NGC 163 (= John Herschel's GC 81, 1860 RA 00 28 55, NPD 100 53.5) is "very faint, very small".

Per Dreyer, NGC 164 (= Marth 12, 1860 RA 00 29 23, NPD 88 02) is "extremely faint". The second Index Catalog adds "Not found by Bigourdan; perhaps = Bigourdan 361 with an error of 1m". (Bigourdan 361 is IC 1560, currently listed as lost or nonexistent)

Per Dreyer, NGC 165 (= Tempel's list V, 1860 RA 00 29 24, NPD 100 53.5) is "faint, large, star in centre, eastern of 2" (the other presumably being NGC 163).

Per Dreyer, NGC 166 (= Leavenworth's list II (#285), 1860 RA 00 29 30, NPD 104 23.0) is "extremely faint, small, slightly extended, 11th-magnitude star to northwest". The second Index Catalog lists a corrected RA (per Howe) of 00 28 46.

Per Dreyer, NGC 167 (= Muller's list II, 1860 RA 00 29 30, NPD 114 09.0) is "very faint, pretty small, irregularly round". The second Index Catalog lists a corrected RA (per Howe and Delisle Stewart) of 00 28 24. (Note: Dreyer's reference to "Muller's list II" is to a paper by Ormond Stone in which observations by Stone, Leavenworth and Frank Muller are presented. According to Steinicke, in this particular case Dreyer accidentally credited Muller with one of Leavenworth's discoveries.)

Per Dreyer, NGC 168 (= Muller's list II (#287), 1860 RA 00 29 30, NPD 113 23.0) is "extremely faint, small, extended 30° east of north, 10th-magnitude star 3 arcmin northeast". The second Index Catalog lists a corrected RA (per Howe) of 00 29 40.

Per Dreyer, NGC 169 (= d'Arrest and the 3rd Lord Rosse, 1860 RA 00 29 30, NPD 66 47.1) is "faint, pretty large, double or binary nucleus, 6th-magnitude star 4 arcmin northeast". (Dreyer credits the report of the discovery to William Parsons, 3rd Earl of Rosse, with the note that most of Rosse's nebular discoveries were actually made by his assistants, George Stoney, Bindon Stoney, and R. J. Mitchell.)

Per Dreyer, NGC 170 (= Marth 13, 1860 RA 00 29 35, NPD 88 52) is "faint, small, round".

Per Dreyer, NGC 171 (= John Herschel's GC 83, 1860 RA 00 29 41, NPD 109 44.1) is "very faint, pretty large, slightly extended, 2 pretty bright stars to southeast". There is also a note questioning whether the object is the same as William Herschel's list III object 223, and a similar note for NGC 175, which suggests that Dreyer was aware of the possibility that NGC 171 and 175 were actually the same object (as turned out to be the case). Note: A Wikisky search for NGC 171 shows the correct object, but is labeled NGC 175, because of the double listing.

Per Dreyer, NGC 172 (= Muller list II (#288), 1860 RA 00 30 00, NPD 113 23.0) is "extremely faint, small, extended". The second Index Catalog lists a corrected RA (per Howe) of 00 30 15, and adds "13th magnitude star close southwest".

Per Dreyer, NGC 173 (= John Herschel's GC 84, 1860 RA 00 30 02, NPD 88 49.8) is "very faint, small, round, very gradually brighter middle, 11th-magnitude star 80 arcsec southwest".

Per Dreyer, NGC 174 (= John Herschel's GC 85, 1860 RA 00 30 02, NPD 120 14.5) is "extremely faint, small, very slightly extended, among bright stars".

Per Dreyer, NGC 175 (= John Herschel's GC 86, 1860 RA 00 30 21, NPD 110 42.2) is "pretty bright, pretty large, extended, gradually brighter middle, mottled but not resolved." There is also a note questioning whether the object is the same as William Herschel's list III object 223, and a similar note for NGC 171, which suggests that Dreyer was aware of the possibility that NGC 171 and 175 were actually the same object (as turned out to be the case).

Per Dreyer, NGC 176 (= John Herschel's GC 87, 1860 RA 00 30 22, NPD 163 56.5) is "extremely faint, small, very slightly extended, mottled but not resolved, 8th-magnitude star near". (In the Small Magellanic Cloud)

Per Dreyer, NGC 177 (= Muller's list II (#289), 1860 RA 00 30 30, NPD 113 12.0) is "extremely faint, small, extended 175°, perhaps a star?". The second Index Catalog says "Delete the (original) query; it seems to be a nebula (per Howe)".

Per Dreyer, NGC 178 (= Ormond Stone's list I (#7), 1860 RA 00 30 30, NPD 104 57.0) is "faint, small, much extended 0°, brighter middle". The second Index Catalog lists a corrected RA (per Howe) of 00 32 06. (See IC 39 for a discussion of the double identification.) Based on recessional velocity of 1445 km/sec, about 65 million light years away, in good agreement with a redshift-independent distance estimate of 60 million light years. Given that and apparent size of 2.2 by 1.0 arcmins, about 40 thousand light years across.

Per Dreyer, NGC 179 (= Leavenworth's list II (#290), 1860 RA 00 30 36, NPD 108 37.0) is "extremely faint, extremely small, round, bright star to northwest". The second Index Catalog lists a corrected RA (per Howe) of 00 30 46.

Per Dreyer, NGC 180 (= John Herschel's GC 88, 1860 RA 00 30 47, NPD 82 06.1) is "very faint, pretty large, irregularly round, star involved to northwest".

Per Dreyer, NGC 181 (= Stephan's list XIII (#6), 1860 RA 00 30 57, NPD 61 17.9) is "extremely faint, extremely small, irregular, very faint star attached".

Per Dreyer, NGC 182 (= John Herschel's GC 89, 1860 RA 00 31 01, NPD 88 02.0) is "very faint, small, irregularly round, very gradually brighter middle."

Per Dreyer, NGC 183 (= Stephan's list XIII, 1860 RA 00 31 03, NPD 61 15.6) is "pretty faint, very small, round, gradually brighter middle". (Note: Dreyer was not aware of Safford's observations at the time he compiled the NGC, as they were published as an appendix to an obscure paper; but he did list a number of Safford's observations in an appendix to the NGC. Unfortunately, he only listed those objects not already in the NGC, so in those cases where Safford was the discoverer of an object already credited to someone else, his prior discovery went unmentioned. Steinicke's book has a complete listing of the objects for which Safford deserves priority, hence his listing as the discoverer of this object.) Stephan's position precesses to RA ?? (TBD)

Per Dreyer, NGC 184 (= Stephan's list XIII (#8), 1860 RA 00 31 09, NPD 61 19.4) is "extremely faint, extremely small".

Per Dreyer, NGC 185 (= John Herschel's GC 90, 1860 RA 00 31 14, NPD 42 26.0) is "pretty bright, very large, irregularly round, very gradually much bright middle, mottled but nor resolved".

Per Dreyer, NGC 186 (= d'Arrest, 1860 RA 00 31 15, NPD 87 36.1) is "faint, small, round, slightly brighter middle". (WORKING: Resolve 'error' in attribution; probably in Steinicke's book)

Per Dreyer, NGC 187 (= Ormond Stone's list I (#8), 1860 RA 00 31 30, NPD 105 25.9) is "faint, small, much extended 150°, brighter middle". The second Index Catalog lists a corrected RA (per Howe) of 00 32 28.

Per Dreyer, NGC 188 (= John Herschel's GC 92, 1860 RA 00 31 40, NPD 05 26.5) is "cluster, very large, round, 150-200 stars from 10th to 18th magnitude".

Per Dreyer, NGC 189 (= John Herschel's GC 93, 1860 RA 00 31 40, NPD 29 42.5) is "cluster, pretty large, round, stars from 11th to 15th magnitude". (Also observed Oct 27, 1829 by John Herschel; and since part of his GC and otherwise unpublished, Dreyer failed to note Caroline's prior discovery.)

Per Dreyer, NGC 190 (= Swift's list V (#8), 1860 RA 00 31 48, NPD 83 42.6) is "very faint, small, slightly extended, several stars near to southwest".

Per Dreyer, NGC 191 (= John Herschel's GC 95, 1860 RA 00 31 53, NPD 99 46.4) is "pretty bright, pretty large, irregularly extended 0°". (The reference to a north-south extension is probably due to NGC 191 being nearly in contact with IC 1563 = PGC 2332 (sometimes referred to as NGC 191A).) IC 1563 is a 14th-magnitude lenticular galaxy (type S0?) in Cetus (RA 00 39 00.1, Dec -09 00 54)

Per Dreyer, NGC 192 (= John Herschel's GC 96, 1860 RA 00 32 03, NPD 89 54.6) is "faint, pretty small, pretty much extended, brighter middle".

Per Dreyer, NGC 193 (= John Herschel's GC 94, 1860 RA 00 32 07, NPD 87 26.4) is "faint, large, preceding of 2, 15th magnitude star close to southwest" (the other object presumably being NGC 204).

Per Dreyer, NGC 194 (= John Herschel's GC 98, 1860 RA 00 32 07, NPD 87 43.9) is "pretty bright, small, round, very gradually brighter middle".

Per Dreyer, NGC 195 (= Tempel's list I (#2), 1860 RA 00 32 08, NPD 99 53.3) is "faint." The second Index Catalog lists a corrected position (per Bigourdan) of RA 00 32 33, NPD 99 58.

Per Dreyer, NGC 196 (= John Herschel's GC 100, 1860 RA 00 32 08, NPD 89 51.4) is "faint, pretty small, round, pretty suddenly much brighter middle".

Per Dreyer, NGC 197 (= Marth 14, RA 1860 RA 00 32 09, NPD 89 53) is "extremely faint, south of h41" (h41 being NGC 196).

Per Dreyer, NGC 198 (= John Herschel's GC 97, 1860 RA 00 32 12, NPD 87 58.2) is "faint, small, very gradually bright middle".

Per Dreyer, NGC 199 (1860 RA 00 32 21, NPD 87 37.9) is "faint, very small, 8th-magnitude star 27s west and 45 arcsec south".
