The Faint Object Spectrograph (FOS) was exchanged with STIS during the Second Servicing Mission and brought back to Earth. The FOS had two modes of operation - low resolution and high resolution. In low resolution mode it reached 26th magnitude in one hour with a resolving power of 250. At high resolution, the FOS reached only 22nd magnitude in an hour, but the resolving power was increased to 0.9 Angstroms at 1200 Angstroms.
