Abstract:
We present a catalog of planetary nebulae in the nearest giant
elliptical galaxy NGC 5128. The catalog consists of positions and
[O III]{lambda}5007 magnitudes for 785 planetary nebulae. This is the
second largest catalog of planetaries, next only to that of the Milky
Way. We also list the coordinates of 32 bright stars from the Guide
Star Catalog and 80 additional reference stars in the survey fields
for astrometric reference during future observations. The positions of
the planetary nebulae are accurate to 0.2" with respect to the Guide
Star Catalog in right ascension or declination.
