Example color composite images of galaxies classified as barred (top row) and spiral (bottom row). These categories are nonmutually exclusive, as many barred galaxies also exhibit clear spiral arms. The filters used to create each composite image are labeled in the top left corner of each panel. The numbers in the bottom row indicate the number of spiral arms identified in the visual classification. The full mosaics of the barred and spiral galaxies can be found at the following two links: bars and spirals.
