We present dramatic new HST/WFC3 images of a bright lensed galaxy at z=1.7 that is magnified and stretched by the lensing cluster RCS2 032727-132623. From imagery in six broad-band filters (from F390W to F160W), we create a lens model, improving on our previous model from ground-based images (Wuyts et al. 2010). With this new lens model, we reconstruct the lensed galaxy in the source plane. The giant arc is magnified by 28x, though some regions of the galaxy are magnified by >200x. The high spatial resolution of the source plane images reveal a great deal of morphological complexity in this star-forming galaxy at z=1.7.
