We report the results of our analysis of the diffuse X-ray background present in the ROSAT PSPC observations of the core of the Pleiades Cluster. We detect the existence of an X-ray shadow in the 0.2-0.41 keV passband coinciding with IRAS emission. However, the depth of this shadow is significantly less than expected, casting doubts on the generality of the X-ray shadowing observed previously with ROSAT .
