Imaging Faint Brown Dwarf Companions Close to Bright Stars with a Small, Well-corrected Telescope Aperture

We have used our 1.6 m diameter off-axis well-corrected subaperture (WCS) on the Palomar Hale telescope in concert with a small inner-working-angle phase-mask coronagraph to image the immediate environs of a small number of nearby stars.
