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 ...

NGC 7686 is a Open Cluster in the Andromeda constellation. NGC 7686 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 5.6, NGC 7686 is easily visible with the help of a small binocular.

The open cluster NGC 7686 is located in the constellation Andromeda. On 15 September it is in opposition to the Sun and hence culminates at local midnight. The best viewing time from Switzerland is in the months January to December.

HD 221246 or NGC 7686 1 is a star in open cluster NGC 7686, and it belongs to the northern constellation of Andromeda. With an apparent visual magnitude of 6.17, [2] it can be viewed by the naked eye only under very favourable conditions. It has a spectral classification of K3III, meaning it is an evolved orange giant star. [3]

NGC 7686 is cataloged as an open cluster in the constellation Andromeda. It is described as poorly populated with 50 to 80 stars. Distance estimates range from 900 to 3000 light years. William Herschel discovered it on December 3, 1787. Since its discovery, like Pluto, astronomers later demoted NGC 7686.
