First Light image (of M51) with the new DESI Corrector Assembly (CA) on the Mayall 4m telescope on Kitt Peak. The CA consists of four ~1m diameter lenses and a two-element atmospheric dispersion corrector, as well as the hexapod, used for fine-motion and focus control of the CA. The image was made with the Commissioning Instrument, composed of five CCD cameras temporarily installed in the DESI focal plane.
