(Left): Hubble Space Telescope ACS/WFC F606W-filter image of NGC 1396 with the pair of background galaxies highlighted. (Center): a zoom-in on the highlighted area, showing the pair of background galaxies (﹩{ \mathcal A }﹩ and ﹩{ \mathcal B }﹩) and a Fornax galaxy globular cluster (GC). The redshifts of the three objects are marked on the image, where the redshifts of the galaxies have been measured from the gas emission lines while that of the GC was measured from the stellar absorption lines. (Right): the same zoom-in area from the middle panel in the MUSE datacube, showing, clockwise from top left, the continuum-subtracted Hα, [O III]₅₀₀₇, [O II]₃₇₂₇, and Hβ emission maps.
