This is the faintest of the telescopically discovered globulars, but that is due in part to
the very high degree of absorption here (5.4m).

Astronomical Leage Program: Messier Club, Messier Binocular Club
Position: 1819-1347
Type: Oc
Dimensions: 6'
Class: II 3mn
Cluster population: 100
Magnitude: 6.5
Notes:
De Cheseaux first made note of it in 1746, noting only the cluster. (The nebula was
not detected until Isaac Roberts photographed the cluster in 1875.)
Messier added it to his catalog on June 3, 1764, and incredibly, hints at the nebula by
this description: "cluster of small stars, mingled with a faint light... with a small
telescope this cluster appears in the form of a nebula." It would seem reasonable that
Messier was simply describing the grainy background this cluster would show in a small,
poor telescope.
It is 66 x 53 light years in diameter. It is 5 million years old, and lies 19,000 light
years from the galactic center and 120 light years above the galactic plane.
It is part of the Ser OB1 association. The brightest star is 8.2m.
The nebula has the mass of 12,500 Suns and is 70 light years in diameter.
Observations:
C8 at 104x. Seems to have two centers, with nebulosity? It contains many "chains"
and doublets. Note the "elephant's trunk" in the middle of the nebula.
14x70 Binos. Four stars resolved and apparent nebulosity or unresolved background
stars.

This cluster is 4 million years old (the earliest spectral type is O9), and it is 21,400

Observations:
C8 at 104x. It resembles a miniature Corona Borealis; dominated by a 6.5m Y star,
plus 7 other stars. The background looked grainy at 104x.
C11 at 98x. It overflowed the field by a factor of 100%. Very, very rich!

Herschel described it as a "loose straggling cluster."

be about 11.0, not 6.0.

The primary is a spectroscopic binary, as well as a pulsating variable. It is 1.9 times
as massive as the sun, and 3 times as large. It is also a Delta Scuti variable and a member
of the Hyades group.
The Sun is travelling in the general direction of Delta and in about 1.25 million years,
Delta will be much brighter in our sky than it presently is due to its proximity. In fact, it
will be the brightest star in our sky.

Notes:
It was first discovered by G. Kirch in 1681. Halley included it in his list of 1715, as
did John Bevis (1786 Celestial Atlas).
De Mairan (1733) included it in a paper he published in 1733 and described it as "a
very dense, small cloud and very similar to the Andromeda Nebula, were it not for the
star which is seen close to the center."
Cassini wrote of it (in 1740) that "one might imagine that they [nebulous stars] are
formed of a great number of extremely small stars, so close to one another that they
- 22 -
Zone 220
cannot be resolved even by our best telescopes. It is the combined light of these which
gives them their irregular shape and whitish color."
De Cheseaux listed it in 1746, calling it "a prodigious cluster of small stars".
Le Gentil listed it in 1759, as did Koehler in 1782. Bode included it in his 1777
catalog.
Messier added it to his list on May 30, 1764. He described it as a "cluster of a large
number of small stars... which can only be seen in a good instrument; with an ordinary
telescope... it resembles a comet: this cluster is mingled with a faint glow; in this cluster
is a star of 8th magnitude."
It is 15 light years in diameter and 550
million years old.
It has a density of 83 stars per cubic
parsec. Robert Tumpler calculated that an
observer at the center of M11 would see
several hundred 1m stars— 40 or more
would be brighter than Venus!!
It lies 23,000 light years from the
galaxy's center.
Observations:
C8 at 104x. An awesome and glorious
sight! Note the dominant Y star (8m) at the
center, and by all means, use high power! A
dark streak in the S is the dark nebula
Barnard 318. The "Wild Duck" name was
coined by William Henry Smyth because he
felt the appearance of the cluster resembled
a flock of ducks in flight. William Herschel
claimed to have seen it with the naked eye.
14x70 Binos. Mottled, triangular shape,
with 9m star about 10m S (makes it look
like a double star).

B5, and 120 stars are known to be members. The brightest star is 10.3m.
It lies 23,000 light years from the galactic center and 250 light years below the

Observations:
C8 at 104x. A triangle of 10m stars dominates this patchy cluster with a neat "kite" at
the center. The overall pattern suggests a tuning fork. (Steve Coe calls it a wishbone
shape.)

Cluster population: 50
Magnitude: 8.9
Notes:
This cluster is 50 million years old, and contains one Cepheid. The brightest star is
