Abstract:
    We present the results of a wide-field [O III] λ5007 survey for
    planetary nebulae (PN) in M87 and its surrounding halo. In all, we
    identify 338 PN candidates in a 16'x16' field around the galaxy;
    187 of these objects are in a statistical sample that extends to
    m5007=27.15.

Description:
    On 1995 April 6 and 7 we surveyed a 16'x16' region of sky around M87
    with the T2KB CCD on the Kitt Peak 4m telescope, which afforded a
    plate scale of 0.47" per pixel. Our on-band data consisted of seven
    exposures totaling 6.8hr through a 30Å full-width-half-maximum
    (FWHM) interference filter centered at 5030Å in the converging
    f/2.7 beam of the telescope.
