NGC 4809 is a Irregular Galaxy in the Virgo constellation. NGC 4809 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its B magnitude of 14.2, NGC 4809 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.
