At 90x it is almost fully resolved. A 7.9-magnitude star in the west stands out.
There are many bright stars in the northwest.
In the east there is a small condensation from where lines of stars extend outward. Also, a line of stars running from the center to the southeast attracts an observer's attention. There is a triangular-shaped clump in the southeast somewhat detached from the cluster. There are many faint stars sprinkled in the outlying areas.
