New scientific results with SpIOMM: a testbed for CFHT's imaging Fourier
  transform spectrometer SITELLE
  We present new data obtained with SpIOMM, the imaging Fourier transform
spectrometer attached to the 1.6-m telescope of the Observatoire du
Mont-M\'egantic in Qu\'ebec. Recent technical and data reduction improvements
have significantly increased SpIOMM's capabilities to observe fainter objects
or weaker nebular lines, as well as continuum sources and absorption lines, and
to increase its modulation efficiency in the near ultraviolet. To illustrate
these improvements, we present data on the supernova remnant Cas A, planetary
nebulae M27 and M97, the Wolf-Rayet ring nebula M1-67, spiral galaxies M63 and
NGC 3344, as well as the interacting pair of galaxies Arp 84.
