[NII] λ 6583 emission mapped by MUSE-WFM (Castro et al. 2018) around Mk 34 with a spatial resolution of approximately 1″. The [NII] λ6583 emission mapped by MUSE-NFM is overplotted in green contours (see Fig. 1). The MUSE-NFM data sample the emission with a spatial resolution of approximately 80 mas and a field of view of 7.5"×7.5" (red square). The cluster R136 is indicated toward the north-west side of the field.
