Enhanced color image, using the three ionization levels of oxygen detectable with the MUSE data: red: [O iii] 5007, green: [O ii] 7320, blue: [O i] 6300, all corrected for extinction using the Balmer decrement. [O i] is partially corrected for sky-line contribution. This representation shows the stratification of the nebula even more clearly than Fig. 10.
