HD 192685, also known as QR Vul or HR 7739, is a star 1,199 ly away in the Vulpecula constellation. It is visible to the naked eye. It is a Be star and is slightly variable. From October to December 1982 the Hydrogen alpha absorption line increased in emission strength by 30%. The line is partially filled by redshifted emission.
HD 192685 has excess infrared emissions (12-100 μm) which are interpreted to be free-free radiation in the gas surrounding the star.
It has at least one companion with separation 0.55" and magnitude 7.55, and may also be a long-period spectroscopic binary.
