HST/F814W images of A68-HLS115 in the image (left panel) and source plane after reconstruction (right panel). White dashed contours represent the Hα clumps and the white solid contours the Hα surface brightness measured in the image (left panel) and source plane (right panel) surface brightness maps corresponding to 0.64 and 1.28 × 10⁻¹⁶ erg s⁻¹ cm⁻² arcsec⁻². The surface brightness is conserved between the image and source plane. The cluster galaxy which is acting as a lens has been removed from the two images.
