Abstract:	We present a technique to measure [Fe/H] and [α/Fe] from individual iron and alpha element lines in medium resolution spectra from the DEIMOS spectrometer (R ∼ 6000) on the Keck ii telescope. The moderate dispersion and multiplexing drastically increase the accessibility of halo and dSph stars not only in the Milky Way, but also M31. Using a grid of spectral syntheses of stellar atmospheres in local thermodynamic equilibrium, we have measured elemental abundances from the metal lines in deimos spectra of individual red giant stars in well-studied Milky Way globular clusters. The abundances are consistent with high resolution studies over a wide range of [Fe/H].
