Caption: Figure 1.

Left: log-stretched JWST F770W image of M82 with dust and stellar continuum and background subtracted, capturing the strength of the 7.7 μm PAH feature. Blank pixels in the center are where the detector is saturated. Right: same as left, but for the F1130W data tracing the 11.3 μm PAH feature. In the top right, the PSF of the final images is shown.
