Caption: Fig. 5.

Composite image obtained from the central parts of the HST I (F814W), H (F160W), and K (F205W) band data. The different objects identified in the single band images are identified. Note the strong similarity between the colors of star P and the other stars in the field. The two quasar images, extremely reddened, are prominent in the red channel of the image (i.e., the K‐band image). Lens SP is visible as a blue fuzz between the quasar images, while lens G, best seen in F160W, is visible as a greenish object (F160W being the green channel of the composite image). Note the low‐redshift (?) galaxy to the south of the lensed quasar.
