Hα emission in Leo P overlaid on the combined F475W + F814W HST image (cyan, yellow and red contours are Hα-emission levels of 5, 10, and 15 × 10⁻²⁰ erg s⁻¹ cm⁻², respectively). The known H II region is the compact blue source in the main southern feature. The MUSE data have also revealed a region of Hα emission just to the north, and two large extended shells to the south and (far) north (see also Fig. 11).
