Position: 0850+1149
Type: Oc
Dimensions: 29'
Class: II 3r
Cluster population: 500
Magnitude: 6.9
Notes:
Messier cataloged it on April 6, 1780.
It is 12 light years in diameter.
Its H-R diagram is closer to a globular cluster than an open cluster, since the brighter
stars have already turned off the Main Sequence. (This turn-off point is at absolute
magnitude +3.5. As clusters age, the leaving point for their stars moves down and to the
right on the Main Sequence H-R diagram. That this leaving point is at such a dim
magnitude suggests that the cluster has been around for an awful long time. In fact, the
H-R diagram suggests an age of 10 billion years for M67! Recently, NGC 188 has been
shown to have a similar spectral composition.) Perhaps one reason it has survived so
long as an open cluster is that it lies high above the plane of the galaxy (1,500 light years
or so).
The brightest star– a B9V– is 9m (about 50 times brighter than the Sun).
This cluster is 5 times as far as the Beehive (M44), also located in Cancer, but is only
1/4 the diameter.

Notes:
1830: 3.2 @ 196. The period is 890 years (Heintz, 1963).
The A star is also a spectroscopic binary with a period of 9.9047 days, and an infrared source.
Observations:
C8 at 697x. Star C is very difficult. Webb said it was "a remarkable system" and
noted colors of Y and B.

Zone 162
Observations:
C8 at 104x. Using an O-III filter, I was just barely able to detect it with tube
movement and averted vision. It is huge, rivaling the Helix, and very, very faint. It is
framed by a parallelogram of faint stars, and overflows the parallelogram a little.
Model (where the Sun is a baseball):
Its diameter would be 1,078 miles.
