Ben 74, ESO069-SC004, GCL-40
RA 16:25:48
Dec -72°12.0'
Globular

Dunlop 68 "A pretty large rather faint
round nebula, about 3.5-4' 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."
h: "Globular cluster, large, faint,
round, very gradually a little brighter in the middle, all resolved into stars
15..18th mag, 4' diam, with stragglers. A delicate and beautiful object."
On a second occasion he called it "pretty bright, large, irregularly round,
gradually brighter in the middle, resolved into stars 13..16th mag; pretty
compressed, diam 5' or 6' by estimation, approx. 50 seconds in RA. A fine
object." His final observation was recorded as "faint, large,
irregularly round, very gradually brighter in the middle, 7' or 8' diameter, all
resolved into stars."
Hartung notes: "In fine contrast with a
field sown profusely with stars is this rather faint but very rich globular
cluster; it is regularly round, rising broadly to the centre, about 3' across
with rays of faint stars emerging. Resolution is apparent with 20cm while 10.5cm
shows plainly an unresolved haze."
Sanford calls it a "faint but rich
globular cluster ... worth a look with larger amateur instruments (10-inch and
up). It is about 3 arcminutes in diameter and begins to resolve well in an
8-inch telescope."
ASV Journal Vol 24 No 3 June 1971: "at
limit in 4-inch at 64x. Dispersed in 12.5-inch at 150x."
11x80: This gentle object
lies near a bright triangle of stars which aid in locating it. Although faint,
it is readily seen when sweeping as a soft, pretty large gentle glow. Its quite
faint, circular glow shows no peaked central concentration. Needs some attention
to see; slightly easier than the galaxy NGC 6744. (exurban skies) [AS]
11x80: “What a wee
one! Exact copy of a 9th magnitude star. Bright stellar nucleus, with an
ever-so-tiny smudge surrounding it, which at times is not apparent - just one of
a field of stars. Strange?!” (urban; seeing good; transparency below
average; dew) [AS]
6-inch f/8.6 Newtonian: Very
challenging in bright moonlight. After careful, sustained study with various
eyepieces I picked it out at 65x by tapping the telescope tube. It shows as an
extremely faint but surprisingly large nebulous patch which can be held once its
position is pinpointed. (suburban skies, bright moonlight) [AS] |
