Colour-composite picture of the SE group. N is up, and E is left. The size of the image is 12.50 × 13.77 arcmin². In the bottom part lie the two overlapping spirals, NGC 3314A\B (see Iodice et al. 2021b), while in the upper right corner lies NGC 3312. In NE, a bright lenticular galaxy is visible, NGC 3316, which is in the background of the group at a similar redshift as the galaxies in the core. The lower right box shows an enlarged region around NGC 3312 to enhance the extended stellar filaments on the SW side of the galaxy, due to RPS. They are marked with the two dashed lines.
