Color composite of the S³MC mosaic for the IRAC 8.0, 4.5, and 3.6 μm wave bands, represented by the colors red, green, and blue, respectively. The prominent regions are N83/N84 at the southeast tip of the wing, N76 in the north, N66/NGC 346 near ﹩\mathrm{R}\,.\mathrm{A}\,.=1^{\mathrm{h}\,}00^{\mathrm{m}\,}﹩ and ﹩\mathrm{decl}\,.=-72^{\circ }10^{\prime }﹩, and the entire southwest region of the bar, which hosts several prominent H II regions such as N22. Because of the arrangement of the different IRAC wave bands in the focal plane of Spitzer, the 3.6 μm data are displaced westward from the 4.5 and 8.0 μm data.
