ROSAT PSPC and HRI observations of the low-power radio galaxies NGC~6251 (z=0.0234) and NGC~4261 (z=0.0089) have shown complicated X-ray structures and spectra. In both objects we find an extended atmosphere and a small-scale bright component associated with the active nucleus. However, the interpretation of this nuclear X-ray emission is complicated by the presence of multiple spectral components, and has remained ambiguous in the absence of X-ray data with good spatial and spectral resolution. Here we propose ACIS observations of these galaxies to determine the fraction of their core X-radiation which originates in non-thermal processes, and to study the gas components of the cores and envelopes. X-ray emission from the jets will also be detectable.
