Query: A multi-object, multi-field spectrometer and imager for a European ELT   One of the highlights of the European ELT Science Case book is the study of
resolved stellar populations, potentially out to the Virgo Cluster of galaxies.
A European ELT would enable such studies in a wide range of unexplored distant
environments, in terms of both galaxy morphology and metallicity. As part of a
small study, a revised science case has been used to shape the conceptual
design of a multi-object, multi-field spectrometer and imager (MOMSI). Here we
present an overview of some key science drivers, and how to achieve these with
elements such as multiplex, AO-correction, pick-off technology and spectral
resolution.
