We detect and resolve HI in eleven galaxies down to a column density of $\\sim10^{20}$ cm$^{-2}$ inside a ~6 deg$^2$ field and with a resolution of ~1 arcmin on the sky and ~8 km/s in velocity. We present HI images, velocity fields and integrated spectra of all detections, and highlight the discovery of three HI clouds -- two in the proximity of the galaxy IC 5270 and one close to NGC 7418. Each cloud has an HI mass of $10^9$ M$_\\odot$ and accounts f","authors_text":"A. E. T. Schinckel, A. Ng, A. P. Chippendale, A. Popping, A. Tzioumis, A. W. Hotan, A. W. Sweetnam, B. Boyle, B.
