NGC 7686 is a moderately-sized open cluster in the constellation Andromeda, containing about 80 stars.[2] At magnitude 5.6, it is an easy target for binoculars and small telescopes.[3]

According to Johnson et al. (1961), the "color-magnitude diagram shows merely a uniform scatter with no significant tendency to show a cluster main sequence". They conclude that this is not actually a star cluster.[4]
