NGC 4945
James Dunlop discovered NGC 4945 = D 411 = h3459 on 29 Apr 1826. This is one of the first objects observed by Dunlop (2nd night in logbook) and the first galaxy he discovered, along with NGC 5128 the same night. His summary description reads, "a beautiful long nebula, about 10' long, and 2' broad, forming an angle with the meridian, about 30 [degrees] south preceding and north following; the brightest and broadest part is rather nearer the south preceding extremity than the centre, and it gradually diminishes in breadth and brightness towards the extremeties, but the breadth is much better defined than the length. A small star near the north, and a smaller star near the south extremity, but neither of them is involved in the nebula. I have strong suspicions that the nebula is resolvable into stars [on 4 June], with very slight compression towards the centre. I have no doubt but it is resolvable. I can see the stars, they are merely points. This is north following the first zeta Centauri." Dunlop made a total of 7 observations (sketch, Figure 17).
NGC 5128
James Dunlop discovered NGC 5128 = D 482 = h3501 on 29 Apr 1826, his second night recording deep sky objects -- NGC 4945 was discovered just 20 minutes earlier! Based on 6 observations, his summary description reads, "A very singular double nebula, about 2.5' long and 1' broad, a little unequal: there is a pretty bright small star in the south extremity of the southernmost of the two, resembling a bright nucleus: the northern and rather smaller nebula is faint in the middle, and has the appearance of a condensation of the nebulous matter near each extremity. These two nebulae are completely distinct from each other, and no connection of the nebulous matters between them. There is a very minute star in the dark space between the preceding extremities of the nebula; they are extended in the parallel of the equator nearly." His sketch (Figure 20) shows two parallel bands with a star between at one end.
IC 5250
James Dunlop discovered IC 5250 = D 255 = D.S. 768 on 5 Sep 1826 with his homemade 9-inch f/12 speculum reflector. He described a "small faint elliptical nebula in the parallel of the equator, about 25" long and 12" or 15" broad." His position is just 3' following this interacting pair of galaxies (similar in appearance to the Antennae). Interestingly, John Herschel discovered NGC 7358, which is just 11' SW, but apparently missed this galaxy, which is larger and brighter.
IC 5332
James Dunlop probably discovered IC 5332 = D 546? on 14 Jul 1826. He reported finding an "extremely feeble, ill defined nebula; it is at least 1' diameter. It seems rather elongated oblique to the equator; it is north following a bright star of the 7th-8th magnitude, and also north of two small stars." His position is 1° south and 1 minute of RA east of IC 5332, which matches his description: a 7th mag star is 13' SW and a 10th mag star (and two 12th mag) are close SW. This identification was suggested by Glen Cozens in his analysis of Dunlop's discoveries.
NGC 5643
James Dunlop probably discovered NGC 5643 = D 469 = h3572 on 10 May 1826 and recorded "an exceedingly faint, extended nebula, about 10' long; rather ill-defined." His position is just 5' east, but his size estimate is a very poor match (transcribed correctly from his handwritten notes). Perhaps he thought a nearby chain of stars was a nebula and the positional match is just a coincidence?
NGC 6300
James Dunlop discovered NGC 6300 = h3668 on 30 Jun 1826. He described (handwritten notes) a "faint round nebula, about 1 1/4' diameter, slightly condensed very gradually to the center - not very well defined at the edge. Preceding and forming a triange with two stars of the 7 and 8th mag." He made 4 more observations in July and Aug., but the discovery is missing in his catalogue, which I assume was an oversight (NGC 1947 is a similar case).
NGC 6744
James Dunlop discovered NGC 6744 = D 262 = h3776 on 30 Jun 1826 with his 9" reflector from Parramatta (20 km W of Sydney). His summary description based on 3 observations reads "a pretty large very faint nebula, about 5' or 6' diameter, slightly bright towards the centre; a minute star is north of the nebula, and two stars of the 7th mag preceding." His rough published position was 1 min 45 sec of time too far west (12' error).
NGC 6861
James Dunlop discovered NGC 6861 = D 425 = h3811 on 30 Jul 1826 and recorded "a very small faint nebula, about 15" diameter." There is nothing at his position, but Glen Cozens found he made a 1° transcription error (to the north) from his handwritten notebook position to his published catalog (verified). The corrected position is just 6' NW of NGC 6861, the brightest galaxy in the area.
NGC 7049
James Dunlop discovered NGC 7049 = D 406 = h3860 on 4 Aug 1826 and recorded "a small round nebula, about 12 or 15 arcseconds diameter, very bright immediately at the centre, resembling a small star surrounded by an atmosphere. This is N.f. a star of the 6th magnitude." His position was 4' ENE of center.
NGC 7083
James Dunlop probably discovered NGC 7083 = D 263? = h3870 on 28 Aug 1826 and recorded "a small faint round nebula, 20 arcseconds diameter, a little brighter in the middle, following a group of pretty bright stars." His position is ~20' too far west. John Herschel found this galaxy on 22 Jun 1835 and logged "F; L; R of lE; vgpmbM; 60"; resolvable; with long attention it appears mottled. Perhaps Dunlop 263, with 3 minute correction in RA." On a later sweep he noted "pB; pL; R; gradually brighter in the middle; 60"." First resolved as a "spiral nebula" on a plate taken at Harvard's Arequipa station around 1900.
NGC 7410
James Dunlop discovered NGC 7410 = D 518 = h3960 on 14 Jul 1826. His summary description based on two observations reads, "a very faint nebula extended preceding and following, about 1.5' long and 20 or 25 arcseconds broad; a little brighter in the middle, or rather nearer the N.p. extremity; the S.f. extremity is very ill defined." His handwritten notes specify the elongaton is SW-NE, clinching the identification.
NGC 7552
James Dunlop discovered NGC 7552 = D 475 = h3977 on 7 Jul 1826 and made 4 observations. He described the first member of the Grus Quartet as "a small faint nebula, rather elongated in the parallel of the equator, about 30" broad, and 40" long; there is a pretty bright point situated near the centre of the nebula: a small star precedes it."
NGC 7582
James Dunlop discovered NGC 7582 = D 476 = h3977 on 7 Jul 1826 and recorded "a small faint round nebula, about 30" diameter: a double nebula follow this [NGC 7590 and 7599]." John Herschel made a single observation on 2 Sep 1836 and described "pB, L, pmE, gradually brighter in the middle." His declination was 15' too large. NGC 7582 was first photographed by DeLisle Stewart at Harvard's Arequipa Station between 1898 and 1901 and the position was corrected.
NGC 7590
James Dunlop discovered NGC 7590 = D 477.1 = h3980 on 14 Jul 1826, along with NGC 7599 and recorded "two very small round nebulae [NGC 7590 and 7599], nearly the same RA, and differing about 1' in polar distances." His single position for the pair was over 30' too far west.
NGC 7599
James Dunlop discovered NGC 7599 = D 477.2 = h3981, along with NGC 7582, on 14 Jul 1826 and recorded "two very small round nebulae, nearly the same RA, and differing about 1' in polar distances." His single position was 30' too far W. John Herschel observed the pair of 2 Sep 1836 (sweep 728) and logged "F; pmE; gradually brighter in the middle; 3'; [the following of two]."
NGC 7689
James Dunlop discovered NGC 7689 = D 347 = h7689 on 5 Sep 1826 and described a "faint round nebula, about 20" diameter." His position was 17' too far ESE, but his notes also mention "preceding a small star" which matches NGC 7689.
NGC 7793
James Dunlop discovered NGC 7793 = D 608 = HN 4 on 14 Jul 1826 and recorded a "faint round nebula, about 2' diameter, with a very slight condensation towards the centre; a double star is north preceding" (2 observations). His position was 14' too far east (typical error) and the double star is probably a wide pair (~1' separation) about 8' N. Apparently John Herschel didn't observe this galaxy from South Africa.
