Other Names: Melotte 58; Collinder 124; Raab 45, M50
Astronomical Leage Program: Messier Club, Urban Deep Sky Club, Messier Binocular
Club
Position: 0703-0820
Type: Oc
Dimensions: 16'
Class: II 3r
Cluster population: 200
Magnitude: 5.9
Notes:
It was discovered by G. D. Cassini in 1711, and Messier added it to his catalog on
April 5, 1772. He came across it while observing the Comet of 1772.
It is 9 light years in diameter. It is 78 million years old, the youngest stars being B6
and B8 types. The brightest star is 9m (165 times brighter than the sun).
It lies 30,000 light years from the galactic center and 70 light years below the galactic
plane.
Observations:
C8 at 47x. Rich! Note the lone R star 7 min SE of the center. William Schaart
(Killeen, TX; a C8) writes, "The central area is sort of a stretched-out pentagon or house
shape."
14x70 Binos. 14 stars counted in a murky sky.
Model (where the Sun is a baseball):
Its diameter would be 4,340 miles with stars 365 miles apart.
Distance (LY): 3,030
Luminosity (suns): 3,130

Astronomical League Program: Herschel II Club
Rating: 3 M
Position: 0718-1312
Type: Gn
Cluster population: 10
Magnitude: 9.0
Dimensions: 6' x 8'
Notes:
The central star (11m) is a Wolf-Rayet star.
Wolf-Rayet stars are very luminous and super-hot (up to 90,000o K) with strong
emission lines of ionized helium, carbon, oxygen, and nitrogen, but few absorption lines.
They were discovered in 1867 by C. J. Wolf and G. Rayet. About 300 are known.
The emission lines arise from a shell of gas that is expanding at speeds up to 3,000
km/sec. This blow-off amounts to 10 suns per 100,000 years, a horrific rate for stellar
winds. They often form ring nebulae because of this.
- 24 -
Zone 209
The average mass of a Wolf-Rayet star is about 10 suns, but they are probably about
20 when they begin their Wolf-Rayet phase. Half of them are binaries, usually with O or
B companions.
It is now believed that Wolf-Rayet stars are the naked cores of Of pro-genitors.
Of stars are very massive, young O stars with enhanced emission lines of helium II
and nitrogen III, plus strong absorption spectrum. The emission lines arise from a
turbulent atmosphere being blown into space by the star. They are the hottest, brightest,
most massive stars known. The current "record holder" is HD 93129A, near Eta Car. It's
surface temperature is 50,000oK; it gives off as much light as 3 million Suns; and has the
mass of 120 Suns!
Observations:
C8 at 47x. The S half is brightest. Discovered by William Herschel in 1785, his son
John wrote (in 1836) that it seemed to resemble "the profile of a bust (head, neck and
shoulders)."
C11 at 120x. (Steve Coe's telescope, Sentinel, Arizona.) The nebula was bright but
not well defined at the edges; it showed a splotchy texture. With a UHC filter, wow!
Donald Duck's bill and skull were very easy and sharply defined against the sky, and the
splotches were more noticeable. In A. J. Crayon's 14-inch Dob with an O-III filter, it was
similar to the C11 with UHC. But with a UHC in the Dob, the view as even more
stunning!

Observations:
C11 at 125x + UHC. Extremely difficult even with the UHC filter. Two 10m stars to
the west make good sky marks. Very faint and no details noted other than shape. Either
the center is suddenly brighter, or I detected the central star— not sure which.

Observations:
C8 at 104x. Bright, large and rich. It
contains mostly W stars. Note STF 1121
just S of the center, and STF 1120 on the
W edge. Webb: "Grand broad group… A

Rating: 2 M
Other Names: Melotte 75; Collinder 159; Raab 62, M46
Astronomical Leage Program: Messier Club, Messier Binocular Club
Position: 0742-1449
Type: Oc
Dimensions: 27'
Class: II 2r
Cluster population: 500
Magnitude: 6.1
Notes:
It was discovered by Messier on February
19, 1771. He noted that "the cluster contains a
little nebulosity."
It is 300 million years old. The youngest
stars are B9 types.
It lies 31,000 light years from the galactic
center and 380 light years above the galactic
plane.
The planetary nebula NGC 2438 is not a
true part of the cluster as the cluster and
planetary are moving in different directions.
Observations:
C8 at 104x. Large, but dim. The planetary
nebula NGC 2438 (on the N side) is easy.
The stars are of 10m-12m, but note the 8m red
star 20 min SW.
Webb: "Beautiful circular cloud of small
NGC 2437 (M46)
stars about 1/2 deg in diameter." LaCaille and
Open cluster (II 2 r; 500 stars)
Observed with C8 on 2/1/92
Earl of Rosse both saw the planetary nebula as

annular. William Schart (Killeen, TX; C8)
writes: "A broad scattering of stars that fills
most of the FOV... No discernible pattern. However, there is an extension off to the SW
that does not seem to be quite as dense. A nice object."

The central star is 75,000o K, but 17.7m.
Observations:
C8 at 104x. Large and faint, it does not magnify well. It is roundish and lies on the N
edge of the open cluster M46. In reality, it lies 1,900 light years closer to earth than the
cluster. Dean Williams, an avid amateur from Arkansas, says he can see some ring
structure at about 140x. I was not so lucky.
