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 206 is the richest and most conspicuous star cloud in the Andromeda Galaxy, and is one of the largest and brightest star-forming regions in the Local Group. [2] It contains more than 300 stars brighter than M b =−3.6. [3] It was originally identified by Edwin Hubble as a star cluster but today, due to its size, it is classified as an OB ...
