Add to ORKGAstrophysical Journal, 653(2): pp. L97-L100.We report the discovery of a cluster-scale lensed quasar, SDSS J1029+2623, selected from the Sloan Digital Sky Survey. The lens system exhibits two lensed images of a quasar at z p 2.197. The image separation of s 22.5 inches makes it the largest separation lensed quasar discovered to date. The similarity of the optical spectra and the radio loudnesses of the two components support the lensing hypothesis. Images of the field show a cluster of galaxies at z1 ~ 0.55 that is responsible for the large image separation. The lensed images and the cluster light l center are not collinear, which implies that the lensing cluster has a complex structure
