NotesThis elliptical galaxy in the central parts of Boötes has a bright nucleus and glows with an orange-yellow colouration. It lies close by another galaxy in the sky, the barred spiral IC 4420, but the two are unrelated; IC 4418 is almost twice as far from the Milky Way as its apparent neighbour.

IC 4418 lies within a rich field of galaxies in south central Boötes. Several other, rather fainter, galaxies are also visible in this image, of which the most prominent are two examples immediately to the south of IC 4418. These two galaxies, PGC 1739567 and PGC 4540292, share an almost direct line of sight, and overlap one another as seen from Earth. Imagery provided by Aladin sky atlas
