  We are conducting a large survey of star formation within ~400 nearby spiral
and irregular galaxies through imaging of the Halpha emission. We present here
some of our first results from 104 of the galaxies in our sample, investigating
the variation of SFR and Halpha 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.
