Images of the full FOV of Chandra (left) and XMM-Newton (right) of MACS J0717.5+3745. The surface brightness excess to the west/south-west are several foreground structures in between us and the cluster, indicated by the ‘foreground emission’ label. The XMM-Newton image is over-saturated in the cluster centre so that this can be seen more clearly. The green dashed circle indicates the approximate R₂₀₀ of the cluster. Intensity scale is in flux per pixel (0.492 × 0.492 arcsec for Chandra, and 4.1 × 4.1 arcsec for XMM pn).
