NGC 6101
James Dunlop discovered NGC 6101 = D 68 = h3623 on 1 Jun 1826 from his backyard observatory in Paramatta NSW. He described "A pretty large rather faint round nebula, about 3.5' or 4' diameter, a little brighter in the middle. There is a very small nebula on the N.p. side joining the margin of the large nebula." The "very small nebula on the N.p. side" is probably a few 12th magnitude stars. Dunlop's position was off by a relatively small 4'.
NGC 6139
James Dunlop discovered NGC 6139 = D 536 = h3628 on 13 May 1826. His summary description (based on two observation) reads, "a round nebula, about 1' diameter, bright immediately at the centre, and very faint from the bright nucleus to the margin. Another observation makes the figure rather elliptical, with a bright nucleus." His position was pretty poor -- 23' east of center.
NGC 6352
James Dunlop discovered NGC 6352 = D 411 on 14 May 1826. He described (summary) "A rather faint nebula, of an irregular round figure, 4' diameter, slightly branched; easily resolvable into stars, with slight compression of the stars to the centre." Dunlop made 6 observations and his published position was ~15' too far east. John Herschel didn't observe this globular from the Cape, so it doesn't have a General Catalog designation.
NGC 6362
James Dunlop discovered NGC 6362 = D 225 = h3684 on 25 Jun 1826 and described a " pretty large rather bright round nebula, 3' or 4' in diameter, very moderately condensed to the centre, resolvable into extremely minute stars; the stars are more scattered on the south side." He also mentioned in his handwritten notes that a star of 7th mag was north preceding and the identification is certain.
NGC 6388
James Dunlop discovered NGC 6388 = D 457 = h3690 on 13 May 1826. His summary description based on 7 observations reads, "a beautiful round nebula, about 5' diameter, with a bright round well-defined disk or nucleus, about 15" diameter, exactly in the centre; this has the appearance of a planet surrounded by an extremely faint diluted atmosphere; there is a small star involved in the faint atmosphere: the atmosphere is at least 6' diameter - Figure 18." His position is just 1.5' south of center.
NGC 6441
James Dunlop discovered NGC 6441 = D 557 = h3705 on 13 May 1826. He made 5 observations and published the description "a small well-defined rather bright nebula, about 20 arcseconds diameter, a very small star precedes it, but it is not involved; following gamma (G) Telescopii."
NGC 6496
James Dunlop discovered NGC 6496 = D 460 = h3715 on 28 Jun 1826 and reported 7 observations. His summary description reads, "a very faint nebula, extended about 2 1/4' in length, oblique to the equator, with a bright point in each extremity; the northern, I think, is a very small star; but the southern of the two, or the one at the southern extremity, is a small nucleus or condensation of the nebulous matter. This follows 16 Telescopii - Figure 19." His sketch shows the globular elongated NW-SE, which is probably due to several brighter stars. Dunlop's position for D 461 (dated as 28 Jun) is 3 minutes of RA too far east with the same declination, so this might be another observation.
NGC 6584
James Dunlop discovered NGC 6584 = D 376 = h3737 on 5 Jun 1826 and described (summary) a "pretty bright round nebula, about 1 1/4' diameter, moderately condensed to the centre; three very small stars involved in the preceding margin." He claims 4 observations and his position is 6.5' due west of center. John Herschel made two observations, first recording on 8 Jul 1834, "globular cluster; B; R; gradually much brighter middle; entirely resolved into stars 16m; easily seen."
NGC 6652
James Dunlop discovered NGC 6652 = D 607 = h3747 with his 9-inch f/12 speculum reflector on 28 Jun 1826. His summary description (3 observations) is "a rather bright well-defined round nebula, about 12 or 14 arcseconds diameter, following a star of the 6th mag." His published position was 33' too far E but his identification is secure and the bright star = HD 171034.
NGC 6723
James Dunlop discovered NGC 6723 = D 573 = h3770 on 2 Jun 1826. His summary description (based on 6 observations) reads "a beautiful bright round nebula, about 3.5' diameter, moderately and gradually condensed to the centre. This is resolvable. The moderate condensation, and the bluish colour of the stars which compose it, give it a very soft and pleasant appearance. This is rather difficult to resolve, although the condensation is not very great." He mentioned (notebook) "It is scarcely so much condensed as M68 which I viewed this evening."
NGC 6752
James Dunlop discovered NGC 6752 = D 295 = h3778 on 30 Jun 1826 at Parramatta Observatory (near Sydney) with his homemade 9-inch f/12 reflector. His summary description, based on 5 observations, reads: "a pretty large and very bright nebula, 5' or 6' diameter, irregular round figure, easily resolved into a cluster of small stars, exceedingly compressed at the centre. The bright part at the center is occasioned by a group of stars of some considerable magnitude when compared with those of the nebula. I am inclined to think that these may be two clusters in the same line; the bright part is a little south of the centre of the large nebula."
