Notes:
It was discovered by John Herschel in 1833 with an 18-inch F/12.8 scope at the Cape
of Good Hope. He described it as a "coarse straggling cluster, not very rich." The fact
that the cluster would have been virtually on Herschel's northern horizon may account for
his describing it as coarse.
The brightest star is 11.0m.
Observations:
C8 at 104x. A pair of 6m star lies 15 min S. This cluster is very, very rich, but faint.
It lies between two brighter stars (8m to NW, 9m to SE). Its charm disappears at high
powers!

Rating: 2 E
Other Names: Chi Per (Double Cluster); Melotte 14; Collinder 25; Raab 10, H VI 34
Astronomical League Program: Herschel 400
Position: 0222+5707
Type : Oc
Dimensions: 29'
Class: I 3r
Cluster population: 150
Magnitude : 6.1
Notes:
Hipparchus and Ptolemy both wrote of it.
It lies 1,100 light years behind NGC 869, so the duplicity is due only to alignment.
Or so said earlier texts. Stefan Keller (Lawrence Livermore National Laboratory) and
Eva Grebel (Max Planck Institute for Astronomy) measured 17,319 stars to fainter than
magnitude 18 in and around the clusters and find that both clusters are 7,300 +/- 170 light
years away and 13 +/- 3 million years old. They really are double!
It lies 33,000 light years from the galactic center and 450 light years below the
galactic plane. 303 members are known, and the earliest stars are B0 and B1 types
approaching Rigel in brilliance (some 60,000 times the Sun’s luminance). There are also
several red supergiants (which are detectable in a small scope, and which rival Betelgeuse
in output and probably size). It is 70 light years in diameter and only 3 million years old.
Observations:
C8 at 37x. It contains many red and blue stars. The center is rather poor.
Model (where the Sun is a baseball):
Its diameter would be 20,000 miles. The stars would be 2,120 miles apart (if we
count the stars counted by Keller and Grebel, they would be 550 miles apart, more typical
of a true open cluster)
