Images of the cluster AP0018 in colour panels (top) produced by combining three passbands and grey-scale panels (bottom) produced from individual passband frames (passbands are labelled inside the panels). Green and red circles mark T and C apertures, respectively. The size of each panel is 10" × 10". An insert at the top-right corner indicates the location of the cluster in M 31. North is up and east is to the left.
