From Sky & Telescope By - Govert Schilling, Edited by - Amal Udawatta The region shown here covers 100×100 arcseconds around the newly discovered galaxy dubbed Nube. The color image is a composite of light collected through the g, r, and i filters. The black-on-white background, imaged in the g and r bands, is shown in reverse color to highlight the galaxy's faint outskirts.
