Abstract (from CDS):

We present R-band observations of the Cosmic Lens All-Sky Survey gravitational lens system B1152+199, obtained with the active optics system at the Telescopio Nazionale Galileo. Owing to the very good spatial resolution of the images (0".6), the optical counterpart of the two quasar components and the lens galaxy have been clearly identified. Contrary to previous estimates, the new location derived for the lens is in excellent agreement with the lensing interpretation for the system. We estimate a time delay of about 30 h–1 days.
