The active galactic nucleus of Cen A was observed in the range of low energy (0.7 to 20 MeV) gamma radiation. The measurements were conducted in a balloon campaign using a Compton telescope. The identification of the source used an imaging technique called the pi-method. In order to simplify the source identification in the pi-charts, these are compared with model charts resulting from Monte Carlo calculations. A thorough understanding of the telescope characteristics (especially the point image function) was decisive for the development of the pi-method. The determined spectral index and the magnitude of the excess agree very well with measurement in the hard X-ray range. The measurement, however, surprises by the significant photon flux in the high energy part of the spectrum, confirming that the luminosity of Cen A in the MeV gamma range is larger than in any other part of the electromagnetic spectrum. Three models to explain the measured spectrum are discussed.
