Caldwell 17 Inset 3
In the ground-based Digitized Sky Survey (DSS) image at upper right, a blue outline shows another area of Caldwell 17 (NGC 147) imaged by Hubble’s Wide Field and Planetary Camera 2 (WFPC2) in visible and infrared light. In that Hubble image, shown at lower left, a red square is centered on a globular star cluster in Caldwell 17 that was later imaged by Hubble’s Wide Field Camera 3 (WFC3), also in visible and infrared light (lower right).
