Imaging of the complete extent of the nearby elliptical galaxy NGC 5128
(Cen-A) in the [O III] 5007A line and in an off-emission band (MB#531/17).
The goal is to obtain a complete census of the planetary nebulae in this
galaxy.

Since the observations are in a narrow and a medium band filter, then the
standard photometric calibration plans do not apply. OB's are enclosed
for observation of a spectrophotometric standard (LTT3864) in the [O III],
H-alpha and MB#531/17 and MB#696/20 filters. Observations of the
standard should preferably be obtained all together or at least in the
following two pairs:
[O III] and MB#531/17;
H-alpha and MB#696/20.
OB's for dome flats in the [O III], MB#531/17, H-alpha and MB#696/20 filters
are provided to reach a mean count of 20000ADU. No sky flats are requested.
