Description:
Tiny, featureless open cluster. At small magnification the most remarkable part is the tight binary in the centre of this sketch. By increasing power, this binary is no longer that spectacular, however the stellar path running down at the Eastern side of the cluster is more pronounced with the four stars nearly in-line. This won't be anyone's favourite open cluster I guess. ;)
