Description:
This cluster is 2,000 light years away and according to Burnham's has about 50 stars brighter than Mag.12.
It can be discribed as being "delicate" and rather "unspectacular" with a small concentration of stars in the center. When using 80X much of the clusters brighter stars can be seen. When the eyepiece is doubled to about 160X the view becomes much narrower but many of the dimmer back ground stars appear.
