10″ × 10″ zooms of the PSR  J1357−6429 (left) and PSR  J1048−5832 images (right) taken through the I_BESS (1800 s) and the v_HIGH filter (24 000 s), respectively. In both cases, the colour scale has been stretched to highlight fainter objects. A flux enhancement (labelled with X) is seen at the Chandra position of PSR  J1357−6429, which might be due either to a background fluctuation or to an unresolved object in the PSF of the two adjacent stars A and B (see text for discussion).
