Abstract: We are conducting a large survey of star formation within ~400 nearby spiral and irregular galaxies through imaging of the Hα emission. We present here some of our first results from 104 of the galaxies in our sample, investigating the variation of SFR and Hα EWs along the Hubble sequence for these galaxies. We find a strong dependence of SFR on Hubble type, peaking for Sbc galaxies, but with large dispersions within each type. There is a possible dependence of SFR on bar presence, but none on group membership. There is an increase in EWs for later Hubble types, but with large dispersions within each type. We find no dependence of EW on bar presence, group membership or on absolute magnitude.
