The Local Group dwarf galaxy IC 10 is currently undergoing an extensive burst of star formation, as indicated by its luminous \ion{H}{2} regions and a high density of Wolf-Rayet stars. As part of a multi-wavelength study, we have obtained images of this remarkable galaxy with H\alpha, H\beta, [\ion{S}{2}], and [\ion{O}{3}] filters at the Apache Point Observatory 3.5m telescope. The complex morphology noted in prior H\alpha observations is seen in the other emission lines, although the high line-of-sight reddening (E(B-V) ~0.85) severely limits our sensitivity in H\beta and [\ion{O}{3}]. We are using these data to identify candidate supernova remnants and Wolf-Rayet shells, and, in conjunction with longslit spectra, to obtain reddening measurements for the major \ion{H}{2} regions.
