Caption: Figure 1.

Deep image of NGC 1052–DF2 obtained with HST/ACS. The total exposure time is 41840 s in F814W and 40,560 s in F606W, 20 orbits each. North is up and east is to the left. The scale bar is for the top panel (∼0.5 kpc at the distance obtained in this work). The bottom panel shows a zoom and reveals resolved red giant stars in a background of unresolved blue stars.
