We present new Hα imaging of all known dwarf irregular companions to NGC 6946: UGC 11583, KK 251, KK 252, KKR 55, KKR 56, Cepheus 1, KKR 59, and KKR 60. The galaxies span a range of blue absolute magnitudes of [ -13.6, -17.6] , relative gas content of [0.1, 2.5] , current star formation activity of yr-1, and timescale to exhaust the current gas supply of [6, 86] Gyr.
Key words: galaxies: dwarf / stars: formation
