We are using full spectrum fitting to determine the ages and metallicities of Galactic clusters (M67 and globular clusters). We find that the method is very accurate to measure the metallicity. Blue horizontal branches are well identified as a ‘young’ sub-component, and the age of the ‘old’ component is in fair agreement with CMD determinations.
