About image
This is a nice couple of globular clusters in Coma Berenices constellation.
M53 is the brightest one on the bottom right of the image, quite concentrated; NGC 5053 (on the upper side of the image) is instead less bright and above all with very poor concentration of stars.
Both clusters are very far from Earth (50000 light years for NGC 5053 and 58000 for M53).
