GMOS-N image

Here we see multiple images of the same lensed quasar at z=2.805 due to the gravity of a less distant massive cluster of galaxies (z=0.49). There are several studies ongoing since the discovery article that can be found here: The Astrophysical Journal
The GMOS-N Image should be rotated 180 degrees to match the others.
Here is an enlarged version of my image with the labels for every recognizable object. The arc is barely visible. A, B, C labes are the multiple images of the quasar, while G1, G2, G3 are the galaxies at the core of the cluster. WD is a foreground white dwarf star.
This last article contains an image obtained with the Hubble Space Telescope.
