Using Hα and Hβ images obtained at the CFHT, we derived the spatially varying reddening within NGC 6537 and NGC 7027. We then corrected the observed Hβ picture for dust extinction to obtain pictures more in accord with radio maps. The left panels below show NGC 6537; the right panels, NGC 7027. The top panels show the observed Hβ picture, and the bottom panels, the Hβ picture corrected for spatially varying extinction. Note that the bright optical knot in NGC 7027 corresponds to a hole in the extinction.
