STF 2323 (39 Draconis) is a quadruple system located 184 light-years from the Sun. The primary component, A, is a white main-sequence star of spectral class A1V with a mass of 2.12 times that of the Sun. The first companion, B, is a yellow-white main-sequence star of spectral class F5V with a mass of 1.18 solar masses, orbiting the primary component with an estimated period of 2455 years. The second companion, C, is the spectroscopic binary HD238865, consisting of a yellow-white subgiant of spectral class F7IV and a red dwarf, orbiting around their common center of mass once every 2.7 days. According to the Washington Double Star Catalog (WDS), component C should be gravitationally linked to components A and B, but the orbital period is unknown; it may be a common proper motion (CPM) companion.

100mm - _STF 2323 can be found nearly midway between the stars Xi and Omicron Draconis. Higher magnification, such as 180x in this case, is required to resolve components A and B. In the telescope, component A appeared yellow-white, while component B appeared gray-blue, deviating from their spectral classes. Component C exhibited an orange tint.
