Colour images of NGC 253 produced by combining broad-band images and emission-line maps extracted from the MUSE data cube. The mosaic covers an area of 20 × 5 arcmin2, and it includes roughly nine million independent spectra. The top panel shows a composition of three broad-band filters. The g band is plotted in blue, the r band in green, and the i band in red (Acknowledgement: ESO/M. Kornmesser). The bottom panel is a composition of emission line maps with [O III]λ 5007 in blue, Hα in green and [S II]λλ 6717,6731 in red.
