A couple of dozen stars are mag 11.5 or brighter and seem to form a continuous loop or exaggerated "S" shape with no central concentration! At 128x, ~80 stars are visible but the cluster is really too large for a good view at this power. Two brighter mag 7 and 8 stars are at the SE end with mag 8.5 and 9 stars near the NW edge. The cluster straddles TrA and Norma and is just visible naked-eye. ARC 3627 (the core of the "Great Attractor"!) lies 1.5 degree SE. ************************************************************ NGC 6026 = PK 341+13.1 = E389-PN7 = PN G341.6+13.7 16 01 20.9 -34 32 39 V = 13.2; Size 54"x36" 18" (7/5/05 - Magellan Observatory, Australia): at 228x, this planetary appeared moderately bright, moderately large, elongated 4:3 SW-NE, ~0.8'x0.6'. Dominated by a mag 13.5 central star with an even surface brightness halo. Nice contrast gain using a UHC filter at 228x. 17.5" (6/30/00): at 220x this fairly faint PN appeared slightly elongated SW-NE, ~50"x35". The 14th magnitude central star is easily visible encased by an evenly lit disc. The edges of the halo appear somewhat ragged but the PN is crisp-edged at 280x using a UHC filter. 13" (7/5/83): very faint, small, round. A very faint mag 14 central star is visible. The planetary is visible with direct vision using a UHC filter. Located 7.3' NW of mag 7.6 SAO 207243. 8": not found. ************************************************************ NGC 6027 = (U10116) = MCG +04-38-005 = (CGCG 137-010) = VV 115 = HCG 79b = Seyfert's Sextet = PGC 56575 15 59 12.5 +20 45 49 V = 14.3; Size 0.4x0.2; Surf Br = 11.7 18" (8/3/05): at 257x, the brightest component of Seyfert's Sextet appeared faint, very small, slightly elongated ~E-W, 15"x10", contains a faint stellar nucleus with direct vision. A mag 14.5 star lies 1' ESE and two additional mag 14.5 stars lie close SE. Just resolved from HCG 79C which lies 22" west of center. 18" (6/20/04): at 320x, a trio of galaxies forming a small equilateral triangle were fairly easily resolved with careful viewing. The brightest of the trio (HCG 79b) is at the NE corner and appeared elongated 3:2 E-W, ~20"x13". The other two members (HCG 79a and HCG 79c) are both extremely small, round, ~10" diameter. Two mag 14.5 stars 1'-1.5' SE are collinear with HCG 79b and a slightly brighter mag 14 star lies 2' W. In a 30" Starmaster, HCG 79e was barely visible (appeared stellar). 17.5" (5/14/88): faint, small, elongated ~E-W. 17.5" (6/6/86): this is Seyfert's Sextet = HCG 79, an extremely compact group! On close inspection, the confused "clump" resolves into three components with the brightest component (HCG 79b) appearing fairly faint, small. Extremely close are HCG 79a = N6027A just 36" SSW and HCG 79c = N6027B 22" W of center. A mag 14.5 star is 1.1' ESE and other faint stars are near. These three galaxies are just resolved at 220x. 13" (6/18/85): slightly elongated E-W. 13" (5/26/84): faint, very small, irregularly round, weak concentration. Seyfert's Sextet was discovered by Edouard Stephan (XII) in 1882. Seyfert's name was attached after a paper in 1951. Although Stephan recorded this ultra-compact group as only a single object, the description "eF, vF* inv, 2 vF st nr" implies he resolved two or probably three member. The GSC position (15 59 12.5 +20 45 49) refers to HCG 79b (most prominent visually). The RNGC does not follow Seyfert's original designations for the members of the group. ************************************************************ NGC 6027A = (U10116) = MCG +04-38-008 = (CGCG 137-010) = VV 115 = Seyfert's Sextet = HCG 79a = PGC 56576 15 59 11.1 +20 45 17 V = 13.9; Size 0.7x0.5; Surf Br = 12.5 18" (8/3/05): very faint, very small, slightly elongated, 15"x10".

Possibly =*, HC. Incorrect identification in the RNGC; (R)N6039 = N6040B. Discovered by Swift (IV). Described as "eeeF, vS, R, sp of 3 in a line, the other 2 being 2 of Stephan's, 3rd of 10." This object is the first listed, though. Discussed by Dreyer in the NGC notes section. This number is applied in RNGC and PGC errata list to N6040B which is attached to the SW end of N6040. See RNGC Corrections #1 and P.A.S.P. Vol 83, p320. The PGC errata lists gives N6039 = M+03-41-073 (from MCG). But Harold Corwin claims NGC 6039 is likely NGC 6042 and Swift's description "sp of 3," should read "sf of 3."

Located 4.5' NW of a mag 9.5 star. Collinear with a faint double star 3' S (13/14.5 at 18"). Incorrect identification in the RNGC and plotted incorrectly on the U2000. The NGC coordinates (obtained by Dreyer from Lewis Swift in private correspondence) are 16 14 25 +62 21 20 (2000). This object was never formally entered in any of Swift's discovery lists prior to the NGC. However, in Swift's list IX in Astronomische Nachrichten 3004, he published a corrected position for N6111 (object #57) at 16 14 16 +63 16.2 (2000). This position corresponds with CGCG 320-014 = M+11-20-007 at 16 14 22.5 +63 15 40 (2000). His description "D* nr s points to it" clinches the identification as this galaxy is collinear with a faint double star 3' S (mag 13/14.5 at 18"). This galaxy is not identified as N6111 in MCG (M+11-20-007) or CGCG (320-014) and is misplotted on U2000. See Addenda sheet to Catalogue Corrections, Thomson and RNGC Corrections #5. Bigourdan measured what he thought might be N6111 at 16 15 29 +62 44 (2000), which is given in the IC 2 notes section but Malcolm Thomson measured Bigourdan's offsets carefully and arrived at a close double star. RNGC misidentifies N6111with IC 1210 at 16 14 30.8 +62 32 15 (2000). Coincidentally, Swift also discovered IC 1210 and it is placed correctly in List IX. So the position of N6111 should be changed to 16h 14.1m +63 19 (1975) and the data changed to describe CGCG 320-014 = M+11-20-007. ************************************************************ NGC 6112 = MCG +06-36-017 = CGCG 196-028 = NPM1G +35.0371 = PGC 57762 16 18 00.5 +35 06 37 V = 13.9; Size 0.5x0.5; SB = 12.4 17.5": fairly faint, fairly small, slightly elongated, weak concentration.

Only able to glimpse repeatedly <25% of time with averted vision. Faintest of trio and situated 1.4' SE of N6145 and 2' NW of N6146 in Abell 2197. Incorrect identification in the RNGC. The Birr Castle observers examined the N6146 field three times (with no specific measurements) but the sketch from 26 May 1849 shows three galaxies on a line with comments: "2 new neb, alpha eF st, beta S." Dreyer apparently later added the parenthetical comment "Query h1957 and h1958 and one Nova." Assuming the direction of drift is down (west), then the sketch shows h1957 = N6145 (beta) and h1958 = N6146 (unlabelled) and the third galaxy (alpha in sketch = GC 4196 = N6147) is either M+07-34-022 or M+07-34-023. But MCG does not identify either of these faint galaxies as N6147 and both MCG galaxies are missing from CGCG. Also, M+07-34-023 is mentioned as a companion to N6146 in the UGC notes at 2.3', PA = 338d, 0.45x0.40 but again without a NGC designation. Based on RNGC positions, it appears that (R)N6147 = M+07-34-022 and (R)N6141 = M+07-34-023. The latter ID is clearly incorrect as Bigourdan's position for N6141 is over 20' southwest, although it also used in the PGC. After two previous failures on N6147, I was finally successful on 7/24/95 although this galaxy was a marginal spot, about 15" diameter and visible <25% of time with averted vision. The position was nearly on a line between N6145 and N6146. So I'd suggest N6147 = MCG +07-34-023 although I'm not aware of any modern catalogue which makes this match. There was no indication of M+07-34-022 less than 1' southwest which appears smaller and fainter on DSS. Looking again at the Rosse sketch, there is a faint star (also labelled as alpha) which is placed below (preceding) N6147. This position corresponds with M+07-34-022, so it very possible that this galaxy was seen as stellar and did not receive a NGC number. ************************************************************ NGC 6148 = 2MASXi J1627040+240536 = PGC 58162 16 27 04.0 +24 05 36 V = 16.1; Size 0.5x0.3; SB = 13.8; PA = 60d 17.5": not found, 5/28/89. ************************************************************ NGC 6149 = UGC 10391 = MCG +03-42-011 = CGCG 109-021 = PGC 58183 16 27 24.3 +19 35 50 V = 13.5; Size 1.1x0.8; SB = 13.2; PA = 22d 17.5": faint, very small, round, bright core, stellar nucleus.

Due to an misprint in Stephan's list XIII, the RA is 10 tmin too large. The position for his comparison star (SAO 141069) is given correctly as 16 16 19.5 - 01 38 55 (2000) and once this correction is applied the recomputed coordinates for N6172 matches IC 1213 = U10352 = M+00-42-003 at 16 22 10.3 -01 30 54 (2000). IC 1213 was discovered by Swift and his position is close enough (9 tsec preceding) to pin down his identification.

The bright nebulosity is split into two large sections by a dark lane which runs N-S. The eastern portion is the most prominent and includes the scattered cluster N6193 and its three brighter stars. On the southern end of this section the nebulosity tapers down towards toward the SW corner, 15'-20' from the core of the cluster. The western rim of the nebula is sharply defined with a locally brighter, crisp edge delineated by the dark river which meanders N-S throughout the field. The eastern and northern ends fade into the rich milky way background field. A nearly perfect ellipse of moderately bright stars is just SW of the main body of the cluster and beyond the edge of nebulosity. Interestingly, the center of this ring is dark except for the eastern border which intersects the bright edge and it spans the two sections of nebulosity. The western portion of the nebulosity extends mostly NW from the elliptical ring and is clearly fainter. The highest contrast is along its eastern rim which run N-S, roughly parallel to its brighter counterpart on the east side of the rift. The nebulosity fades towards the north and west with no well-defined edge but again is quite extensive. The listed dimensions of 20'x12' only covers the brightest portion of this much more extension HII/dark nebula complex. 8" (7/13/91 - Southern Baja): very large faint nebulosity which envelops open cluster N6193, about 20' diameter. Extends roughly E-W through the cluster but also a very long brighter streak oriented N-S extends mainly to the south on the west side of cluster. This streak is well defined with an abrupt edge but there is no contrast gain with a UHC filter. 8": faint, moderately large, low surface brightness glow on the W side of open cluster N6193.

Many stars are arranged in strings and loops including a distinctive streamer attached on the SE side which heads south and curves west forming a semicircle and another string is attached on the west side of the core and precedes the cluster. Several chains of stars are also resolved over the 6' core. A dark "lane" protrudes into the core on the SE side. Running along the north edge of the core is a starless strip or a long dark lane which separates the central region from the northern outer halo members. Three small dark lanes in the core converge forming a "Y" which is referred to as the "Propeller".

Discovered by JH (h3650) and observed on sweep 455. h's position is 1.4 tmin E of N6216 (observed 3 times on different sweeps). His descriptions appear to describe the same object. RNGC identifies this object as N6222, Lynga as N6216 and ESO as N6216 = N6222. From Corwin: NGC 6216 = NGC 6222. JH recorded the cluster on four different sweeps. On three of those (NGC 6216), his RA is accurate. However, the fourth sweep (NGC 6222) has the RA 1 min 20 sec following; the Dec is the same. The description for N6222 fits N6216, and there is only a Milky Way star field at N6222's position.

The halo appears to extend to nearly 14' although the star density is very low in the outer edge of the halo. The inner halo is sharply concentrated with a very bright 5'x4' core which is elongated SW-NE. The cluster is highly resolved into mag 12/13 stars from edge to edge with the stars very densely packed over the core. A second layer of mag 13/14 stars is superimposed over the core. The halo contains a number of strings including a long string to the south which curves east and a string to the north which curves west. Also two parallel linear strings head N or NNE from the core. 13": very bright, fairly large, intense core richly covered with fairly bright stars. Scores of stars are resolved in the outer halo. 8": bright lively core highly resolved. The outer halo is highly resolved with several long, distinct streamers. ************************************************************ NGC 6255 = UGC 10606 = MCG +06-37-014 = CGCG 197-018 = PGC 59244 16 54 47.1 +36 30 07 V = 12.7; Size 3.6x1.5; SB = 14.4; PA = 85d 17.5": very faint, moderately large, very diffuse, low even surface brightness, elongated 5:2 E-W.
