On the top right, a full ground based image of a distant galaxy, bright white in the center surrounded by clouds of dust and gas. Bottom left of the image is the Hubble shot of the same area, much closer with stars spotting the black background.

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).
