Some preliminary results of an on-going, deep, multi-band imaging survey is presented. This survey utilizes 15 intermediate-band filters which are sandwitched in between the bright night-sky emission lines and covers the 3000Å -- 10000Å range with Δ λ / λ ~ 0.05 spectral resolution. Our goal is to achieve a depth of AB mag of 25.5 ~ 26.0 in all these 15 bands over an total area of 0.5 square degree centering on HDF-North and HDF-South, and measure the SED of all the objects in the field down to that limit. Two of the many usages of this unique data set are discussed: 1) photometric redshift of galaxies can be derived to an unprecedented accuracy of (Δ z/(1+z) ~ 0.02); 2) the three reddest filters are particularly powerful in finding objects at redshift z ~ 6. Some results from our pilot run on imaging HDF-South with CTIO 4m + 8k*8k MOSAIC are shown to demonstrate the later case. Acknowledgment : H. Yan thanks the Sigma Xi Grants-in-Aid for the support.
