NGC 7686 is a moderate-sized open cluster in the constellation Andromeda, containing about 40 stars. At magnitude 5.6, it is an easy target for binoculars and small telescopes.[1]

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.[2]
