Composite-colour image mosaic of Eridanus 2 as observed with MUSE-Faint. Sloan Digital Sky Survey filters g, r, and i were used for the colours blue, green, and red, respectively. Images of the five separately reduced fields were combined with Montage, and the colours were composited using the algorithm from Lupton et al. (2004). The 72 member stars with MUSE-Faint measurements are circled in green. Celestial north is up. The angular and physical scales at the distance of Eridanus 2 are indicated in the bottom left corner.
