Negative representation of the WFI R-band image (see www.eso.org/public/images/eso1207a/; image credit: ESO) with superposed contours of the smoothed apparent surface brightness of the diffuse X-ray emission in the 0.5 − 7 keV band (point-sources have been excised). The contour levels are drawn at levels of 1.9,2.1,2.6,3.4, and 4.0 × 10^-9 photons s^-1 cm^-2 arcsec^-2. The blue lines mark the borders of the 17′ × 17′Chandra/ACIS-I field-of-view. The position of the O-star multiple system HD 92 206 is marked.
