M53 & NGC5053 in Coma Berenices

Do you own a small telescope? If you do, take it out in the garden and point it towards the Coma Berenices constellation. The brightest star you will detect in this constellation, Alpha Com, will show you the way to a magnificent object duo. Two globular clusters are twinkling next to each other, in a 2° field of view. The globular cluster M53 (left) is 5000 lights years further away from the Earth than its fainter neighbor NGC5053 (right). Both star clusters are moving apart from each other.
