Hα imaging observations of 125 galaxies obtained with the 2.1 m telescope of the San Pedro Martir Observatory (SPM) (Baja California, Mexico) are presented. The observed galaxies are mostly Virgo cluster members (77), with 36 objects in the Coma/A1367 supercluster and 12 in the clusters A2197 and A2199 taken as fillers. Hα+[NII] fluxes and equivalent widths, as well as images of the detected targets are presented.
