In order to optimize observing in the time available, a field in the northern continuous viewing zone (CVZ) was selected and images were taken for 10 consecutive days, or approximately 150 orbits. Shorter 1-orbit images were also obtained of the fields immediately adjacent to the primary HDF in order to facilitate spectroscopic follow-up by ground-based telescopes. The observations were carried out from 18-30 December 1995, and the data are available to the community for study. http://www.stsci.edu/ftp/science/hdf/hdf.html Archive Research 2 http://archive.stsci.edu/siap/search.php?id=HDF& GET Pointed 360.0 360.0 360.0 360.0 0 0 0 100 189.2 62.22 0.3 0.3 HST Optical
