    Abstract

    Two deep K-band (2.2 μm) images, with point-source detection limits of K = 25.2 mag (one sigma), taken with the Keck Telescope in subfields of the Hubble Deep Field, are presented and analyzed. A sample of objects to K = 24 mag is constructed and V606 - I814 and I814 - K colors are measured. By stacking visually selected objects, mean I814 - K colors can be measured to very faint levels; the mean I814 - K color is constant with apparent magnitude down to V606 = 28 mag.
