Description:
Cluster can easily be distinguished from the background stars. Since the
cluster is so large, it does not fit to the eyepiece at 72X. Stars are widely
seperated. But there is a condensation through the center of the cluster. There
is a rectangle, its corners formed from 3 bright relatively stars and one
fainter star. Condensation takes place in this rectangle. But still there are
voids between stars. There are no particular bright stars. There is a balance
between the numbers of bright and faint stars. Most of the stars are whitish
blue but there is a remarkable orangish star in the south-east of the center of
the cluster.
