在室女座星系团的中心附近，一串被称为马卡里安链的星系延伸穿过这张望远镜的视野。在右下方的框架中，由突出的透镜状星系M84（底部）和M86锚定，你可以沿着链的平缓弧线向上和向左。在中心附近，你会看到一对相互作用的星系NGC 4438和NGC 4435，有些人称之为马卡里安之眼。据估计，室女座星系团距离我们有5000万光年远，它本身就是离我们最近的星系团。它拥有大约2000个成员星系，对我们自己的本星系群有着明显的引力影响。在室女座星系团中，马卡良星系链中至少有7个星系看起来是一致运动的，而其他星系可能只是偶然出现在这个星系链中。

Near the heart of the Virgo Galaxy Cluster, a string of galaxies known as Markarian's Chain stretches across this telescopic field of view. Anchored in the frame at bottom right by prominent lenticular galaxies, M84 (bottom) and M86, you can follow the chain's gentle arc up and toward the left. Near center you'll spot the pair of interacting galaxies NGC 4438 and NGC 4435, known to some as Markarian's Eyes. An estimated 50 million light-years distant, the Virgo Cluster itself is the nearest galaxy cluster. With up to about 2,000 member galaxies, it has a noticeable gravitational influence on our own Local Group of Galaxies. Within the Virgo Cluster at least seven galaxies in Markarian's Chain appear to move coherently, while others may appear to be part of the chain by chance.
