Lensed quasar MG0414+0534
The image is an infrared colour composite of the quadruply lensed quasar system MG0414+0534 made by combining 20 min ISAAC J (1.25µm) and Ks (2.16µm) exposures. This complex of images is only about 2 arcsec across. At the centre is the red galaxy at redshift z = 0.96 which is responsible for the four (of which two are not completely resolved) gravitationally lensed images of a z = 2.64 quasar plus a faint arc.
