     High angular resolution PC1 images of the gravitational lens systems HE 1104-1805 and J03.13 are presented. Using a method described in Remy et al. (1997a), optimal TinyTim PSFs are constructed to fit at best the lensed point-like components. The derived photometry of the GL components and the detection of the lens galaxy for HE 1104-1805 are discussed. Textbook case FOS spectra of J03.13 A and B clearly show that this double QSO is a cosmic mirage.
