Zooming in to a higher resolution makes it possible to distinguish the two main stars of the 24 Comae Berenices system as they show distinct vertical diffraction spikes, with the brighter B component to the east (left) and the fainter A component slightly to the west (right). Just visible on the southern edge of this image is the spiral galaxy NGC 4539, a northern outlier of the Virgo Cluster. Imagery provided by Aladin sky atlas
