Cluster population: 1,000
Magnitude : 10.0
Notes:
It was discovered by Carloyn Herschel.
It is 50 light years in diameter and 1.6 billion years old, so its earliest stars are B9
types. The brightest star is 10.0m.
It lies 31,000 light years
from the galaxy's center and
560 light years below the
galactic plane.
Observations:
C8 at 65x. It shimmers, like
the Wild Duck (M11). Use
low powers. Higher powers
suggest two curving dark lanes
cutting into the cluster.
C11 at 115x. Grand sight!
Many, many stars, mostly
faint, and with a moderate
spread in magnitudes. Too
numerous to count; the field
looked grainy it is so rich.
Model (where the Sun is a
baseball):
Its diameter would be 8,710
miles, and its stars would be
434 miles apart.
