A very beautiful object. The cluster is large and members are bright.
It is very easy to count at least 30 stars in this cluster. The orange color of
BM Scorpi is very prominent. BM Scorpi seems to be the brightest of the members
of this cluster. A parallelogram, formed by the four bright members including
BM Scorpi is an interesting asterism.
