A broad-band image of the SMC N33 region obtained through filter R (ESO #813). Same field size and orientation as in Fig. 1. The arrows I and II show the directions of the spectrograph slit. Seeing 06 FWHM. The H ii region apparently contains three stars (numbered #1, #2, and #3). The brightest stars of the field are also numbered. The cross indicates the position of the candidate planetary nebula reported by Jacoby & De Marco (2002).
