Abstract • We present high-resolution Near-Infrared Camera and Multiobject Spectrometer images of random fields obtained in parallel to other Hubble Space Telescope observations. We present galaxy number counts reaching H_1.6=24. The H_1.6-band galaxy counts show good agreement with the deepest I- and K-band counts obtained from ground-based data. We present the distribution of galaxies with morphological type to H_1.6<23. We find relatively fewer irregular galaxies compared with an I-band sample from the Hubble Deep Field, which we attribute to their blue color rather than to morphological K-corrections. We conclude that the irregulars are intrinsically faint blue galaxies at z<1.

Based on observations made with the NASA/ESA Hubble Space Telescope, obtained from the data archive at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.
