Caption: Figure 1.

grz color composite imaging of COOL J0335−1927 from Magellan Telescopes LDSS3-C. The three quasar images are marked in green. The lensing critical curves, the points of maximum magnification for a source at a specified redshift, are computed at the quasar’s redshift z = 3.27 and shown in red. Several other multiply imaged background sources are seen in the vicinity of the quasar images and are shown in the zoomed-in panels on the right. The white boxes mark the three LDSS3-C long-slit observations.
