Bennett 78
ESO331-SC004, GCL-43
RA 16:27:42
Dec -38°50.8'
Globular
cluster |
Dunlop 536 “a round nebula, about 1'
diameter, bright immediately at the centre, and very faint from the bright
nucleus to thge margin. Another observation makes the figure rather ellliptical,
with a bright nucleus.”
h: “pB, R, pgbM, resolvable, with left
eye I can barely discern a few of the stars.” On a second occassion he
called it “B, R, pgbM, resolvable, 2'.” His third observation was
recorded as “vB, R, pL, pgmbM, 2.5'. Evidently a globular, but moonlight
very bright and near full, and I cannot see the individual stars.” The
final record reads: “B, R, psbM, 200 arcseconds, resolvable.”
Hartung notes that with a 12-inch the cluster “appears
granular with glimpses of very faint outliers. It is about 1.5' across, a fairly
symmetrical round haze, quite plain with a four-inch.”
Tom Lorenzin: “10M; 4' diameter; bright,
large and round unresolved glow with brighter center.”
Steve Coe, observing with a 17.5” f/4.5
at 100X, notes: “Bright, pretty large, very bright in the middle at 100X.
Going to higher power at 165X, it has a stellar nucleus and two stars are
resolved in good seeing. Averted vision makes it grow.”
11x80: “Inconspicuous”
pretty much sums it up. Careful observation shows a faint patch, looking like an
extended faint star. Easy once you know where to look. [AS]
8-inch Meade: Bright, small
round globular cluster, with a very bright middle. I can't resolve any stars,
only a little haziness to the edges in a medium starfield. [MS]
15.5-inch f/9 Newtonian:
Easy to find, appears pretty bright has a concentrated nucleus - the nucleus is
about 20” across, much like the disk of the planetary NGC 6153 which lies
nearby. (suburban skies) [AS] |
