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.
