Arp Classification - Galaxy with large
high surface brightness companion. In the 16" at 298x (N7) this
is a nice double system elongated NW-SE about 2'x.5' in size.
6621 has a small bright almost stellar core with a small nuclear
region surrounding it. It has small bright arms extending NW-SE
from the core about .4' in length. There is a very faint haze
starting from the NW arm sweeping around to the SE that pops in
and out with averted vision. 6622 is in contact with 21 at the
end of the SE arm and is slightly elongated perpendicular to the
axis of the main galaxy and has fairly even brightness with very
little central brightening. The arms of 21 are almost as bright
as 22. - Bob Hill |

18" (7/21/04): at 435x, it was fairly clear that
there were two shells in the main body which were of different
sizes and orientations creating a complex appearance. Surrounding
the high surface brightness main body was a thin, very faint outer
envelope (inner portion of the outer envelope). The central star
was visible continuously. |

is easily visible continuously with direct vision. The disc is

with averted. Located 4' SE of a mag 9.5 star. Collinear with

18" (7/22/06): this fascinating planetary was viewed
at 435x. The overal shape is rectangular with the two longer sides
oriented NW to SE. Both ends are noticeably brighter giving an
annular appearance. The NW end is slightly brighter and irregular
in surface brightness with a brighter spot or two. The rim of
the NW end is slightly bowed out and has a well-defined boundary
edge in the interior. The rim at the SE end of the planetary is
unusually straight and well-defined and with averted vision it
appeared to extend slightly beyond the main body of the planetary.
The bright lobe at this end is bar-shaped and extended SW to NE,
in the direction of the minor axis. |

17.5" (7/14/99): this globular forms an unusual
pair with planetary N6445 just 21' NNE and is situated within
a string of four mag 11-12 stars oriented NW-SE. It appears fairly
faint, round, at least 2' diameter. At 280x the diffuse halo increases
to a moderately bright, round core. Although the globular appears
granular, there was no resolution is good seeing except for a
very faint star which was intermittently visible off the north
edge of the core. |

The very irregular halo appears more extensive on the NE side

the cluster and involve the surrounding region though this may
be an optical effect. This is the third brightest globular in
integrated magnitude (V = 5.2) and a difficult naked-eye object

oriented E-W and contains 6 stars (these are possible cluster
members). Within this shallow arc is a 20" knot just east of the
midpoint and this is probably the core of the globular. The entire
string is superimposed on a rich Milky Way background so it was

dark nebula B86. Roughly 75 stars are visible in a 6' diameter.
The "Inky" black dark nebula B86 to the east wraps around the
cluster like a tentacle along the south side and also appears
to wind through a large portion of the cluster. In the cluster's
core is a very dense perfectly circular group of about two dozen
stars in a 1.5' diameter punctuated with the brightest star at
the exact center! Enveloping this core is a dark void except for
a few stars which break through to the north. Surrounding this
irregular dark annulus is a 6' incomplete oval ring formed by
six brighter and several fainter stars. Located in a rich star

18" (7/21/04): at 92x roughly 200 stars are visible
in this beautiful naked-eye cluster. There are four bright mag
6-7 stars in the main group which form a perfect parallelogram
with longer sides of 7' oriented WSW-ENE and shorter sides of
4' oriented NW-SE. A string of stars connects the two stars on
the long southern side of the parallelogram (the star at the SE
vertex is orange tinged BM Sco) with a nice double star embedded
in the string. The NW vertex is part of a bright isosceles triangle
with two mag 8-9 stars and ~7' further NW of this star is a small,
nice asterism consisting of a trio and a double. Also a wedge-shaped
group of 7 stars extends between this NW vertex (which also has
two additional fainter companions) and the SW vertex (short side
of parallelogram) Another distinctive string of stars runs through
the center of the parallelogram roughly parallel to the two long
sides. A nice mag 9/10 double resides along the long northern
side of the parallelogram. An additional mag 7 star is the SW
of the parallelogram. Around the main group there are numerous
scattered stars and the cluster does not have a distinct border.
Over 70 stars in the cluster are brighter than 11th magnitude. |

Corwin originally equated Lacaille's N6634 with
M69. This implies a 1¡ error in the dec of N6634 too far south.
But Glen Cozens argues that the globular is fainter than others
seen by Lacaille and the position is further out than any others
seen by him. At or near his position, though, is a small group
of 4 stars that may be the intended object. Corwin now feels this
interpretation is more likely (see NGCBUGS). Listed as nonexistent
in the RNGC but not equated with M69. |

18" (7/21/04): at 92x at least 300 stars are visible
in the cluster, though very difficult to count due to the very
large size (overfills the 42' field). The more concentrated part
of the cluster spans perhaps 30' and includes a dozen stars of
mag 7.5 or brighter in the main body. This cluster is much larger
and brighter (very prominent naked-eye), but it is much more scattered
than M6 and so is less impressive. There are several bright, distinctive
strings in the cluster including a N-S string of ~8 stars on the
east side of the central region. An equilateral triangle of mag
6, 7 and 8 stars with sides of 3' is on the NW side of the core
