Caroline's Cluster is shown as an inset image from a Digitized Sky Survey ground-based image of C58, which has a much thicker concentration of stars.

C58 Inset Image

Taken by the Digitized Sky Survey (DSS), the ground-based image of Caldwell 58 (NGC 2360) in the lower left shows the location of Hubble’s Advanced Camera for Surveys (ACS) observation of stars in the cluster. ACS uses two imaging chips that are close but not immediately next to each other, leaving a small gap in the full image.
