MW clusters, LG stars, LV HII regions, high$z dwarfs & clusters and deep cosmological fields! High spectral resolution (R 10000) for chemical tagging of stellar and gas kinematics of (p)pn and nearby galaxies, stellar kinematics of MW clusters and face$on galaxy disks.! Intermediate spectral resolution (R 5000) with broad wave$ length$coverage for spectral classification, ionized$gas diagnostics in PN and HII regions, stellar$population studies in nearby and distant galaxies (including field$galaxy redshift determination and cluster membership and dynamics). 8
