Abstract: The 61cm Varese telescope and its Multi Mode Spectrograph operated in the Echelle mode is used to observe nearby Red Clump stars in the Solar neighborhood, with more distant ones being targeted by Asiago 1.22m and 1.82m telescopes. So far high resolution, high S/N spectra of 260 program RC stars have been obtained (85 on a 2nd epoch) providing radial velocities accurate to 0.7 km/s, Teff to 56 K, logg to 0.21 dex, and [M/H] to 0.11 dex.
