This famous galaxy has several alternative names: The Silver Coin Galaxy, the Silver Dollar Galaxy, and Caldwell 65. It’s not easy to find something new in such an easily observed and imaged object. Here I attempted to minimize the distractions in the background and emphasize the galaxy’s interior details. That turned out to be a fulfilling project because the Sculptor is loaded with colors and structures. Be sure to zoom in on this image. This is an RGB image, processed with a synthetic luminance.
