Caption: Figure 2.

Examples of the variation in cluster resolution with distance. The left panel shows the M31 cluster PC1017, at a distance of 0.785 Mpc (Johnson et al. 2012). The middle and right panels show image simulations of this cluster at roughly twice and four times the distance of M31 (1.57 and 3.14 Mpc). The image is in the F814W filter, and has been smoothed and rebinned to simulate the two further distances.
