NGC 7686 (also OCL 251) is a magnitude +5.6 open star cluster located 3,000 light-years away in the constellation Andromeda.

The cluster was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Windsor Road in Slough, Berkshire, on the 3rd December 1787. 

Right Ascension 23^h 30^m 07.3^s, Declination +49° 08' 03"
