We present far-UV imaging of the Hubble Deep Field North (HDF-N) taken with the Solar Blind Channel of the Advanced Camera for Surveys (ACS/SBC) onboard HST. Combined with archival STIS imaging, the full WFPC2 deep field has now been observed at 1500 Angstroms. In the mosaic of 14 ACS/SBC pointings, we detect more than 80 galaxies. No sources are found without counterparts in the WFPC2 image. Redshifts (spectroscopic or photometric) for the detected sources are in the range z=0.07 to z=0.85. We compare morphological properties in the FUV, optical, and near-IR. We investigate the population of UV-bright, intermediate redshift starbursts by measuring the FUV number counts. The galaxy counts reach fainter than AB=28, but dark current glow causes the detection area and completeness to be a strong function of position on the detector.
