Historical Identification: Per Dreyer, NGC 7750 (= GC 5010 = JH 2267 = WH III 427, 1860 RA 23 39 28, NPD 86 58.7) is "considerably faint, pretty large, very little extended 0°, a little brighter middle, 11th magnitude star to southeast".
Physical Information: Based on a recessional velocity of 2940 km/sec, NGC 7750 is about 135 million light-years away, in good agreement with admittedly uncertain redshift-independent distance estimates of 60 to 135 million light-years. Given that and its apparent size of 1.6 by 0.8? arcmin, it is about 65 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7751 (= GC 5013 = JH 2269 = WH III 437, d'Arrest, 1860 RA 23 39 49, NPD 83 54.3) is "faint, small, round, gradually brighter middle, extremely mottled but not resolved".
Physical Information: Based on a recessional velocity of 3245 km/sec, NGC 7751 is about 150 million light-years away. Given that and its apparent size of 1.0 by 1.0? arcmin, it is about 45 thousand light-years across.

Physical Information: Based on a recessional velocity of 3065 km/sec, PGC 141134 is about 145 million light-years away, just a few million light-years closer than its apparent companion, NGC 7751. Given that and its apparent size of 0.8 by 0.4? arcmin, it is about 35 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7752 (= GC 6226, 3rd Lord Rosse, d'Arrest, 1860 RA 23 39 59, NPD 61 16.5) is "faint, small, a little extended, preceding (west of) h 2268", (JH) 2268 being NGC 7753. The position precesses to RA 23 47 01.8, Dec +29 30 09, about 2.6 north-northeast of the galaxy listed above, and in fact to the northwest of NGC 7753, so that barring the reference to h 2268, it might well have been thought that that was Mitchell's object, despite the description not matching the larger, brighter galaxy. However, since the only object to the west of h 2268 is the galaxy listed above, and it fits Mitchell's description, it is obvious that there was some sort of blunder in the NGC position, and the identification of PGC 72382 as NGC 7752 is certain.
 The error in the position is discussed by Gottlieb as follows: "...while observing NGC 7753 at Birr Castle. He (Mitchell) noted "south preceding [NGC 7753] is a very small oblong nebula, resolvable?". This proves that the galaxy to the southwest of NGC 7753 must be what became NGC 7752. Gottlieb then states that d'Arrest "...independently found this galaxy... (but) confused the orientation and place NGC 7752 1.5 arcmin north of NGC 7752, instead of 1.6 arcmin south. As a result the relative positions in the NGC are incorrect." ('north of NGC 7752' is obviously a typographical error, and should read 7753; I have sent a note to Gottlieb and when he corrects the error I will remove this sentence.)
Discovery Note: 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.
Use By The Arp Atlas: NGC 7752 is used (with NGC 7753) by The Arp Atlas of Peculiar Galaxies as an example of a spiral galaxy (NGC 7753) with a large high surface brightness companion (NGC 7752), with the note "Double arm leading to companion."
Physical Information: Since NGC 7752 and 7753 are a physically interacting pair, they must be at the same distance. Under such circumstances, their distance should be based on a combination of the information available for both of them (see NGC 7753 for the calculation involved, which indicates a distance of about 220 to 225 million light-years). Given their presumed distance and NGC 7752's apparent size of about 0.55 by 0.25 arcmin for the main galaxy and about 0.9 by 0.45 including faint outer regions (from the images below), the central region of the galaxy is about 35 thousand light-years across, and its outer regions span about 55 to 60 thousand light-years.
Use By The de Vaucouleurs Atlas: NGC 7752 is used by The de Vaucouleurs Atlas of Galaxies as an example of type I0 pec, and since that essentially agrees with other references, that is the type shown in the description line above.

Historical Identification: Per Dreyer, NGC 7753 (= GC 5011 = JH 2268 = WH II 213, 1860 RA 23 40 05, NPD 61 17.9) is "considerably faint, considerably large, very little extended, very gradually a little brighter middle, mottled but not resolved". The position precesses to RA 23 47 07.9, Dec +29 28 45, about 0.7 arcmin east-southeast of the center of the galaxy listed above and within its outline, the description fits and there is nothing comparable nearby, so the identification is certain.
Use By The Arp Atlas: NGC 7753 is used (with NGC 7752) by The Arp Atlas of Peculiar Galaxies as an example of a spiral galaxy (NGC 7753) with a large high surface brightness companion (NGC 7752), with the note "Double arm leading to companion."
Physical Information: Since NGC 7752 and 7753 are a physically interacting pair, they must be at the same distance. Under such circumstances, their distance should be based on a combination of the information available for both of them. The recessional velocity of NGC 7752 relative to the Cosmic Microwave Background is about 4735 km/sec, while that for NGC 7753 is about 4815 km/sec. Based on their average recessional velocity of about 4775 km/sec (and H₀ = 70 km/sec/Mpc), the pair is about 220 to 225 million light-years away, in almost inevitable agreement with widely varying redshift-independent distance estimates of about 80 to 225 million light-years. Given that and NGC 7753's apparent size of about 3.6 by 1.7 arcmin (from the images below), the galaxy and its outer arms span about 230 to 235 thousand light-years.
Use By The de Vaucouleurs Atlas: NGC 7753 is used by The de Vaucouleurs Atlas of Galaxies as an example of type SAB(rs)bc, and since that essentially agrees with the NED classification, it is the "type" given in the description line for this entry.

Historical Identification: Per Dreyer, NGC 7754 (Leavenworth list I (#266), 1860 RA 23 40 25, NPD 107 24.0) is "extremely faint, very small". The second IC lists a corrected RA (per Howe) of 23 41 58.
Physical Information: Based on a recessional velocity of 7500 km/sec, NGC 7754 is about 350 million light-years away. (Need to do relatisvistic correction for the distance.) Given that and its apparent size of 1.5 by 1.0? arcmin, it is about 150 thousand light-years across.

Physical Information: Based on a recessional velocity of 8100 km/sec, PGC 72509 is about 375 million light-years away, or about 25 million light-years more distant than NGC 7754. (Need to do relatisvistic correction for the distance.) Given that and its apparent size of 0.3 by 0.1? arcmin, it is about 35 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7755 (= GC 5012 = JH 4005, 1860 RA 23 40 36, NPD 121 17.8) is "bright, considerably large, round, pretty suddenly much brighter middle".
Physical Information: Based on a recessional velocity of 2960 km/sec, NGC 7755 is about 140 million light-years away, in fair agreement with redshift-independent distance estimates of 85 to 120 million light-years. Given that and its apparent size of 3.8 by 2.9? arcmin, it is about 150 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7756 (4th Lord Rosse, 1860 RA 23 41 22, NPD 86 40) is "a nebula, 5 arcmin southwest of h 2270", (JH) 2270 being NGC 7757.

Historical Identification: Per Dreyer, NGC 7757 (= GC 5014 = JH 2270, 1860 RA 23 41 37, NPD 86 36.1) is "very faint, considerably large, very little extended, very gradually a little brighter middle, two 13th magnitude stars to north".
Physical Information: Based on a recessional velocity of 2955 km/sec, NGC 7757 is about 135 million light-years away. Given that and its apparent size of 2.6 by 1.7? arcmin, it is about 100 thousand light-years across. The "small high brightness companion" that caused this galaxy to be listed as Arp 68 is the oblong object on the western side of the galaxy (pointed out in the wide-field view by an arrow). Although its appearance is similar to a small amorphous galaxy, it is not believed to be a separate object, but a star-forming region within the larger galaxy old enough that its hottest, brightest stars have already died. As a result it does not have a separate official designation (it is, however, listed in NED as UM 007 NED01, at RA 23 48 41.6, Dec +04 10 36).

Historical Identification: Per Dreyer, NGC 7758 (Muller list II (#475), 1860 RA 23 41 39, NPD 112 49.0) is "extremely faint, very small, irregularly round, suddenly brighter middle, 10th magnitude double star 50 seconds of time to northeast".
Physical Information: Based on a recessional velocity of 13085 km/sec, a straightforward calculation indicates that NGC 7758 is about 610 million light-years away. However, for objects at such distances, we must take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 580 million light-years away at the time the light by which we see it was emitted, about 590 million years ago (the difference between the two numbers being due to the expansion of the intervening space during that time). Given that and its apparent size of 0.7 by 0.5 arcmin, NGC 7758 is about 120 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7759 (Swift list VI (#?), Leavenworth list I (#267), 1860 RA 23 41 54, NPD 107 19.1) is "very faint, small, round, a little brighter middle, bright star to north". The second IC lists a corrected RA (per Howe) of 23 41 41.
Discovery Notes: This is one of a number of objects in a prepublication version of Swift's list VI that was sent to Dreyer just before the publication of the NGC, which were inadvertently left out of Swift's published list VI. In many cases Swift corrected the error by including the missing objects in his list IX, but he failed to do that for this object; so though we know from the NGC that Swift observed the object, there is no known record of the actual date or Swift's measured position and comments.
Physical Information: Based on a recessional velocity of 7325 km/sec, NGC 7759 is about 340 million light-years away. (Should use relativistic correction for distance calculation.) Given that and its apparent size of 1.3 by 1.0 arcmin, it is about 130 thousand light-years across. NGC 7759 is physically interacting with the object to its east (PGC 72499).

Physical Information: Based on a recessional velocity of 7345 km/sec, PGC 72499 is about 340 million light-years away, the same distance as NGC 7759 (which see for images), and they are a physically interacting pair. (Should do a relativistic correction for the distance of the pair.) Given that and its apparent size of 0.5 by 0.15 arcmin, the galaxy is about 50 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7760 (= GC 5015 = JH 2271 = WH III 854, 1860 RA 23 42 08, NPD 59 47.8) is "considerably bright, very small, round, pretty suddenly brighter middle, 12th magnitude star attached".
Physical Information: Based on a recessional velocity of 5250 km/sec, NGC 7760 is about 245 million light-years away (although a drastically different measurement of 13200 km/sec implies a distance of nearly 600 million light-years). Given that and its apparent size of 1.0 by 1.0? arcmin, it is about 70 thousand light-years across (but the larger recessional velocity and distance, if correct, would imply a size of 170 thousand light-years).

Historical Identification: Per Dreyer, NGC 7761 (Ormond Stone list I (#268), 1860 RA 23 42 25, NPD 104 10.0) is "faint, very small, round, gradually brighter middle, 10th magnitude star 8 arcmin to west". The second IC notes "Not found by Howe". Also noted in the second IC (at NGC 7776) is the comment: "7776 and 7761: Howe only found one nebula (IC 5361), RA 23 44 16, NPD 104 09.5, with a 9th magnitude star 3.5 arcmin to the west".
Physical Information: Based on a recessional velocity of 7190 km/sec, NGC 7761 is about 335 million light-years away. (Should do relativistic correction for the distance.) Given that and its apparent size of 1.2 by 1.2 arcmin, it is about 115 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7762 (= GC 5016 = JH 2272 = WH VII 55, 1860 RA 23 42 05, NPD 22 45.8) is "a cluster, pretty rich, pretty compressed, stars from 11th to 15th magnitude".
Physical Information: Approximately 15 to 20 arcmin wide. A relatively young cluster, with many hot blue stars.
Image Notes: The DSS photomosaics below are the best available closeups of the region near NGC 7762, but their quality is uneven because the cluster is on the outskirts of a large emission nebula, Cederblad 214, a small portion of which is seen as reddish-brown clouds scattered throughout the image, and the DSS photomosaic is much redder or not nearly red enough in various oddly shaped regions covering difficult parts of the field; so it is hard to correct for the photomosaic errors without substantially altering the color balance. The corrections I applied to the 24 arcmin wide image and the very wide images are fairly good, but the one degree wide image still has a number of more or less obvious artifacts.

Below, a 3 degree wide DSS image showing the position of the 1 degree image above (outlined by a white border); note the rotation of the smaller image, caused by the difference in projection from the celestial sphere onto a flat image, due to different centering of the images. Such differences are often seen in overlapping portions of different sky atlas charts.

Below, a comparison of the image above to a HST/ESA/FITS Liberator adjustment of the DSS data (outlined in white, to show its position relative to the original image; FITS Liberator image credits and HST site links shown at following image). Despite the posting of this image on the HST site the image was not constructed using HST data. Instead, the software techniques used on HST images were applied to the same DSS images shown above. As a result, although the Liberator images are better corrected for artifacts and use slightly different color-adjustments, they look more like the images above than not.

Historical Identification: Per Dreyer, NGC 7763 (Leavenworth list I (#269), 1860 RA 23 43 25, NPD 107 23.0) is "extremely faint, very small, round, faint star to east". The second IC lists a corrected RA (per Howe) of 23 43 03.
Physical Information: Based on a recessional velocity of around 5550 km/sec, NGC 7763 is about 260 million light-years away. Given that and its apparent size of 0.7 by 0.4 arcmin, it is about 55 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7764 (= GC 5017 = JH 4006, 1860 RA 23 43 34, NPD 131 31.0) is "bright, pretty large, round, gradually brighter middle".
Physical Information: Based on a recessional velocity of 1695 km/sec, NGC 7764 is about 80 million light-years away, in fair agreement with a redshift-independent distance estimate of 65 million light-years. Given that and its apparent size of 2.0 by 1.5 arcmin, it is about 45 thousand light-years across.

Physical Information: Based on a recessional velocity of 9160 km/sec, PGC 72755 is about 425 million light-years away. (Need to do relativistic correction for distance.) Given that and its apparent size of 0.7 by 0.2 arcmin, it is about 85 thousand light-years across. Given its proximity to PGC 72762 (which see for images) and the peculiar appearance of that galaxy, the galaxies may be gravitationally interacting.

Physical Information: Based on a recessional velocity of 9160 km/sec, PGC 72762 is about 425 million light-years away. (Need to do relativistic correction for distance.) Given that and its apparent size of 1.3 by 0.7 arcmin, about 160 thousand light-years across. It is about the same distance as PGC 72755 and PGC 72769, and given their proximity and the peculiar appearance of PGC 72762, it is probably gravitationally interacting with those galaxies.

Based on a recessional velocity of 8845 km/sec, PGC 72769 is about 410 million light-years away. (Need to do relativistic correction for distance.) Given that and its apparent size of 0.4 by 0.3 arcmin, it is about 50 thousand light-years across. Given its proximity to PGC 72762 (which see for images) and the peculiar appearance of that galaxy, the galaxies may be gravitationally interacting.

Historical Identification: Per Dreyer, NGC 7765 (= GC 5018, 3rd Lord Rosse, 1860 RA 23 43 47, NPD 63 36.5) is "very very faint, 100 arcsec northwest of h 2273", (JH) 2273 being NGC 7768.
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: Based on a recessional velocity of 7650 km/sec, NGC 7765 is about 355 million light-years away. (Need to do relativistic correction for distance.) Given that and its apparent size of 0.7 by 0.7 arcmin, it is about 75 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7766 (= GC 6227, Copeland (using Lord Rosse's 72-inch telescope), 1860 RA 23 43 52, NPD 63 39.0) is "very faint, small, 85 arcsec south of h 2273", (JH) 2273 being NGC 7768.
Physical Information: Apparent size about 0.5 by 0.2? arcmin.

Historical Identification: Per Dreyer, NGC 7767 (= GC 6228, Copeland (using Lord Rosse's 72-inch telescope), 1860 RA 23 43 53, NPD 63 41.3) is "very faint, small, a little extended, star 19 arcsec to west".
Physical Information: Apparent size about 1.0 by 0.2? arcmin.

Historical Identification: Per Dreyer, NGC 7768 (= GC 5019 = JH 2273, 1860 RA 23 43 53, NPD 63 37.6) is "very faint, small, extended, star involved, star very near to west".
Physical Information: Apparent size about 1.6 by 1.3? arcmin.

Historical Identification: Per Dreyer, NGC 7769 (= GC 5020 = JH 2274 = WH II 230, 1860 RA 23 43 58, NPD 70 37.7) is "pretty faint, pretty small, round, much brighter middle".
Discovery Notes: NGC 7770 was discovered by Stoney during an examination of the region near NGC 7769, whence the discovery information shown above.
Physical Information: The brightest member of the NGC 7771 group, which consists of NGC 7769, 7770, and 7771. Based on a recessional velocity of 4210 km/sec, NGC 7769 is about 195 million light-years away. Given that and its apparent size of 3.2 by 2.7 arcmin, it is about 180 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7770 (= GC 5021, 3rd Lord Rosse, 1860 RA 23 44 17, NPD 70 40.9) is "very faint, very small, irregularly round, southern of 2", the other being NGC 7771.
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.
Physical Information: A member of the NGC 7771 group, which consists of NGC 7769, 7770, and 7771 (which see for images). Based on a recessional velocity of 4115 km/sec, NGC 7770 is about 190 million light-years away. Given that and its apparent size of 0.7 by 0.4 arcmin, it is about 40 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7771 (= GC 5022 = JH 2275 = WH II 231, 1860 RA 23 44 19, NPD 70 40.0) is "pretty bright, pretty large, extended 84°, brighter middle, northern of 2", the other being NGC 7770.
Physical Information: A member of the NGC 7771 group, which consists of NGC 7769, 7770, and 7771. Based on a recessional velocity of 4275 km/sec, NGC 7771 is about 200 million light-years away. Given that and its apparent size of 2.4 by 1.1 arcmin, it is about 140 thousand light-years across. In images of the members of the NGC 7771 group, noticeable extensions of their fainter outer regions show the effects of their gravitational interaction. Eventually, all three galaxies in the group should merge to form a single galaxy.

Historical Identification: Per Dreyer, NGC 7772 (= GC 5023 = JH 2276, 1860 RA 23 44 38, NPD 74 31.4) is "a cluster of scattered 10th magnitude stars".
Physical Information: Apparent size 5? arcmin.

Historical Identification: Per Dreyer, NGC 7773 (= GC 5024 = JH 2277 = WH II 851, 1860 RA 23 45 05, NPD 59 30.5) is "pretty faint, considerably small, round, 13th magnitude star near to northeast".
Physical Information: Apparent size 1.2 by 1.2? arcmin.

Historical Identification: Per Dreyer, NGC 7774 (Swift list IV (#100), 1860 RA 23 45 12, NPD 79 18.2) is "extremely faint, small, round, in center of 3 stars".
Physical Information: Apparent size 1.0 by 0.6? arcmin.

Historical Identification: Per Dreyer, NGC 7775 (Stephan list XIII (#98), 1860 RA 23 45 19, NPD 62 00.3) is "very faint, pretty small, a little extended, gradually a little brighter middle".
Physical Information: Apparent size 0.9 by 0.8? arcmin.

Historical Identification: Per Dreyer, NGC 7776 (Ormond Stone list I (#270), 1860 RA 23 45 30, NPD 104 10±), is "extremely faint, very small, a little extended, gradually brighter middle". The second IC notes: "7776 and 7761: Howe only found one nebula (IC 5361), RA 23 44 16, NPD 104 09.5, with a 9th magnitude star 3.5 arcmin to the west". As noted at NGC 7761, that is considered to be the same as IC 5361; how the second IC comment relates to NGC 7776 will be dealt with in the next iteration of this page.
Physical Information: Apparent size about 0.9 by 0.3 arcmin.

Historical Identification: Per Dreyer, NGC 7777 (= GC 6229, Stephan list VIII (#30), 1860 RA 23 46 07, NPD 62 29.7) is "very faint, very small, round, brighter middle".
Physical Information: Apparent size 1.2 by 0.8? arcmin.

Historical Identification: Per Dreyer, NGC 7778 (= GC 5025 = JH 2278 = WH III 231, 1860 RA 23 46 11, NPD 82 54.3) is "considerably faint, small, round, pretty suddenly brighter middle, stellar, 1st of 4", the others being NGC 7779, 7781 and 7782.
Physical Information: Apparent size 1.0 by 1.0? arcmin.

Historical Identification: Per Dreyer, NGC 7779 (= GC 5026 = JH 2279 = WH III 232, 1860 RA 23 46 19, NPD 82 54.0) is "pretty faint, small, round, pretty suddenly brighter middle, stellar, 2nd of 4", the others being NGC 7778, 7781 and 7782.
Physical Information: Apparent size 1.4 by 1.1? arcmin.

Historical Identification: Per Dreyer, NGC 7780 (Stephan list XII (#96), Swift list IV (see below), 1860 RA 23 46 23, NPD 82 39.6) is "very faint, very small, round, a little brighter middle, faint star involved".
Discovery Notes: There is no object in Swift's list IV that corresponds to this nebula, and Steinicke's database states that it is an unlisted object from Swift's list XII, which makes no sense, as all the objects in that list are in the IC, not the NGC. I suspect that as in the case of NGC 7759, this is one of the objects inadvertently omitted from Swift's published list VI, but Dreyer transposed the I and V, turning VI into IV.
Physical Information: Apparent size 0.9 by 0.5? arcmin.

Historical Identification: Per Dreyer, NGC 7781 (= GC 5027 = JH 2280, 1860 RA 23 46 39, NPD 82 55.0) is "faint, small, round, 3rd of 4", the others being NGC 7778, 7779 and 7782.
Physical Information: Apparent size 0.8 by 0.2? arcmin.

Historical Identification: Per Dreyer, NGC 7782 (= GC 5028 = JH 2281 = WH III 233, 1860 RA 23 46 45, NPD 82 48.5) is "pretty faint, pretty large, a little extended, gradually a little brighter middle, 4th of 4", the others being NGC 7778, 7779 and 7781.
Physical Information: Apparent size 2.2 by 1.3? arcmin.

Historical Identification: Per Dreyer, NGC 7783 (= GC 6230, Marth #591, 1860 RA 23 46 59, NPD 90 24) is "faint, small, a little extended".
Physical Information: Apparent size about 1.3 by 0.6? arcmin. The brightest member of Hickson Compact Group 98 (= Arp 323).

Physical Information: Apparent size about 0.7 by 0.5? arcmin. A member of Hickson Compact Group 98 (= Arp 323). See NGC 7783 for images.

Physical Information: Apparent size about 0.2 by 0.2? arcmin. A member of Hickson Compact Group 98 (= Arp 323). See NGC 7783 for images.

Historical Identification: Per Dreyer, NGC 7784 (Stephan list XIII (#99), 1860 RA 23 48 06, NPD 69 01.1) is "very faint, extremely small, a little brighter middle, mottled but not resolved?, western of 2", the other being NGC 7786.
Physical Information: Apparent size 0.5 by 0.5? arcmin.

Historical Identification: Per Dreyer, NGC 7785 (= GC 5029 = JH 2282 = WH II 468, 1860 RA 23 48 10, NPD 84 51.8) is "pretty bright, pretty small, irregularly round, pretty suddenly brighter middle, mottled but not resolved, 8th magnitude star 4.5 arcmin to west".
Physical Information: Apparent size 2.5 by 1.3? arcmin.

Historical Identification: Per Dreyer, NGC 7786 (Stephan list XIII (#100), 1860 RA 23 48 14, NPD 69 11.4) is "pretty faint, pretty small, a little extended, very faint star involved, eastern of 2", the other being NGC 7784.
Physical Information: Apparent size 1.0 by 0.7? arcmin.

Historical Identification: Per Dreyer, NGC 7787 (= GC 6231, Marth #592, 1860 RA 23 48 41, NPD 90 13) is "very faint, small, round".
Physical Information: Apparent size 1.8 by 0.5? arcmin.

Historical Identification: Per Dreyer, NGC 7788 (= GC 5030 = JH 2283, 1860 RA 23 49 43, NPD 29 23.3) is "a cluster, small, pretty rich, very compressed, stars of 10th magnitude and from 13th magnitude".
Physical Information: NGC 7788 is thought to be about 7700 light-years away, which probably puts it in the Perseus Arm of the galaxy. Approximately two dozen fairly bright stars lie within a 4-arcmin diameter, which corresponds to 9 light-years at the estimated distance. Based on the turnoff point of its Main Sequence stars, it is about 40 million years old. Its distance is sufficiently uncertain that it may form a double cluster with NGC 7790, which lies about a quarter-degree to the southeast.

Historical Identification: Per Dreyer, NGC 7789 (= GC 5031 = JH 2284 = WH VI 30, Caroline Herschel, 1860 RA 23 49 59, NPD 34 03.8) is "a cluster, very large, very rich, very much compressed, stars from 11th to 18th magnitude".
Physical Information: NGC 7789 is about 8000 light-years away, which probably puts in the Perseus Arm of the galaxy. Several hundred stars lie within a 25-arcmin diameter, which corresponds to 60 light-years at the estimated distance. At about 1.6 billion years of age, most of its upper Main Sequence stars have died, and the 2 to 3 solar mass stars now dying have red giant lifetimes long enough to fill the relatively rich cluster with bright, reddish "dots".

Historical Identification: Per Dreyer, NGC 7790 (= GC 5032 = JH 2285 = WH VII 56, 1860 RA 23 50 01, NPD 29 33.8) is "a cluster, pretty rich, pretty compressed".
Physical Information: NGC 7790 is thought to be about 9600 light-years away, which probably puts it in the Perseus Arm of the galaxy. Approximately two dozen fairly bright stars lie within a 5 by 2 arcmin region, which corresponds to 14 light-years at the estimated distance. Based on the turnoff point of its Main Sequence stars, it is about 55 million years old. Its distance is sufficiently uncertain that it may form a double cluster with NGC 7788, which lies about a quarter-degree to the northwest.

Historical Identification: Per Dreyer, NGC 7791 (= GC 5033 = JH 2286, 1860 RA 23 50 47, NPD 80 00.3) is "very faint, very small, a faint star?, [d'Arrest not found]".

Historical Identification: Per Dreyer, NGC 7792 (= GC 6232, Stephan list V (#15), 1860 RA 23 50 55, NPD 74 17.0) is "extremely faint, extremely small, brighter middle".
Physical Information: Apparent size 1.0 by 0.8? arcmin.

Historical Identification: Per Dreyer, NGC 7793 (= GC 6233, G. P. Bond, (Dunlop 608), 1860 RA 23 51 17, NPD 123 20.7) is "like a comet (1850)". The first IC notes "Occurs in the Cordoba DM, RA 23 50 38, NPD 123 22.3.
Discovery Notes: At the time Dreyer compiled the NGC it was thought that none of Dunlop's observations corresponded to this object; but in recent years an effort has been made to see whether some of his "poor" observations were actually valid, and as indicated by the credit in parentheses, it is now thought that this object was Dunlop's #608.
Physical Information: NGC 7793 is a member of the Sculptor Group of galaxies, one of the nearest group of galaxies to our Local Group. Its recessional velocity of 225 km/sec is too small to provide a reliable estimate of distance, but the 10 million light-year value obtained by ignoring that happens to be in reasonable agreement with redshift-independent distance estimates of 10 to 20 million light-years. Given that and its apparent size of 9.3 by 6.3 arcmins, the galaxy is about 35 thousand light-years across.

Historical Identification: Per Dreyer, NGC 7794 (= GC 5036 = JH 2288 = WH III 466, d'Arrest, 1860 RA 23 51 23, NPD 80 03.2) is "very faint, pretty small, irregularly round".
Physical Information: Apparent size 1.3 by 1.0? arcmin.

Historical Identification: Per Dreyer, NGC 7795 (= GC 5034 = JH 2287, 1860 RA 23 51 34, NPD 30 45.7) is "a cluster, very large, poor, a little compressed, stars of 7th magnitude and from 10th magnitude".
Physical Information: Apparent size 16? arcmin.

Historical Identification: Per Dreyer, NGC 7796 (= GC 5035 = JH 4009, 1860 RA 23 51 45, NPD 146 14.3) is "pretty bright, considerably small, round, gradually much brighter middle".
Physical Information: Apparent size 2.2 by 1.9? arcmin.

Historical Identification: Per Dreyer, NGC 7797 (= GC 5037 = JH 2289 = WH III 867, 1860 RA 23 51 50, NPD 87 08.4) is "extremely faint, pretty small, irregularly round, a little brighter middle".
Physical Information: Apparent size 1.0 by 0.9? arcmin.

Historical Identification: Per Dreyer, NGC 7798 (= GC 5038 = JH 2290 = WH II 232, 1860 RA 23 52 16, NPD 70 01.7) is "pretty faint, small, round, suddenly brighter middle, 10th magnitude star to southwest".
Physical Information: Apparent size about 1.4 by 1.3? arcmin. The galaxy is listed as a pair with NGC 7817, with a probable separation of about 2 million light-years.

Historical Identification: Per Dreyer, NGC 7799 (= GC 6234, d'Arrest, 1860 RA 23 52 21, NPD 59 29.1) is "very faint, very small, 16th magnitude star close to west". The position precesses to RA 23 59 29.3, Dec +31 17 40, just over 20 arcsec west of a pair of stars. d'Arrest's paper states that his "nebula" is 20 arcsec northeast of a 16th magnitude star, and although the brighter star is actually 14th magnitude, it is just over 20 arcsec southwest of the fainter star, which must be d'Arrest's "nova", and is therefore listed above as NGC 7799. However, a number of references misidentify the galaxy to the southwest of the pair of stars (PGC 73156) as NGC 7799, despite the fact that its faint nucleus makes it far too faint for d'Arrest to have seen, and it is essentially certain that the star above, and not the galaxy, is the actual NGC object. Still, given the number of erroneous references to the galaxy, it seems appropriate to discuss it in the following entry.

Historical Misidentification: As noted in the entry for NGC 7799, PGC 73156 is sometimes misidentified as that object; but it is far too faint to have been seen by d'Arrest.
Physical Information: Apparent size of about 1.25 by 0.2 arcmin (from the images below). Vr 5000 km/sec. Redshift-independent distance estimates 60.7 to 87 Mpc.
