MUSE images of the strongest lines in the V1425 Aql nova shell. They were obtained by summing the flux within a certain spectral range after subtracting the continuum. They were smoothed using a Gaussian kernel, and the values below the background median value plus one sigma were masked. The position of the binary is marked with a black cross, and the white marks indicate the position of the nearby stars in the field. Most of the observed emission traces the inner shell, and the outer shell is observed only in [OIII], Hα+[NII], and [OII].
