NGC 5566 is the largest and brightest member of a trio of galaxies that are part of the Virgo Cluster. The others are the 13.2 magnitude NGC 5560 to the upper right (north west) and the 13.7 magnitude NGC 5569 to the upper left. It is possible that these galaxies are interacting with each other as disks of all three seem to be distorted.
NGC 5576 is a fairly large and bright in Virgo. NGC 5560 and NGC 5569 were visible in the same field.143x.
