Comparison of RS Oph images in radio, infrared and X-rays. Left: an image of radio synchrotron-emitting plasma with NIR contours overlaid (Chesneau et al. 2007). Right: the X-ray image obtained after SER and PSF deconvolution processing (same as panel (d) in Figure  1). The X-ray feature extends along the same direction as the NIR and radio features, suggesting that they could all be related. Note that the two panels show very different scales.
