Emission lines in galaxies are a valuable source of information, allowing the study of starformation activity, the identification of active galactic nuclei, among others. The filterconfiguration of S-PLUS, a wide field 12 photometric band (5 broad and 7 narrow) surveyobserving the Southern Sky, is ideal to detect emission by its combination of narrow andbroad bands. An interesting topic to investigate is the characteristics of the emitters inhigher density environments. Do they present a specific location within the cluster? Howdoes the emission morphology appear in these galaxies: distributed in clumps or mostlynuclear? Such analysis can give us clues about the formation of a given cluster. In thiscontext, the Fornax cluster is a great target to be analyzed, as the Hα emission line is locatedwithin the J0660 band, and its proximity provides large enough galaxies to study theiremission spatial distribution. We developed a code that performs a pixel-to-pixel applicationof the Three Filter Method to S-PLUS images in order to create Hα maps for Fornax membersderived by literature compilation. In this contribution we will present the methodology, anddiscuss the results associated with the Fornax phase-space diagram.
