TFOSC -- TUBITAK Faint Object Spectrograph and Camera
Low and medium resolution imaging spectrometer TFOSC (TUBITAK Faint Object Spectrograph and Camera) was build at Copenhagen University Observatory, and is similar in its layout to DFOSC at Danish 1.54-m, ALFOSC at NOT and to other instruments of this serie. The instrument was built under the order by TUBITAK observatory.
