Abstract:
    We present the results of a planetary nebula survey of galaxies in the
    Leo I group performed with the Kitt Peak and Cerro Tololo 4m
    telescopes and on-band off-band λ5007 interference filters. In
    all, we detected 249 PN candidates populating the top 1.5mag of the
    planetary nebula luminosity function (PNLF), including 93 in the E0
    galaxy NGC 3379, 54 in the E6 galaxy NGC 3377, and 102 in the S0
    spiral NGC 3384.
