The Hubble Deep Field
The Hubble Deep field is located at
12h 36m 49.4000s +62d 12' 58.000" (J2000 Equinox).
The location of the HDF is shown superimposed on a
KPNO R band image obtained
by Peter Eisenhardt with the 4-meter telescope.
The HDF is the central field shown in yellow.
In addition, short exposures were taken at the positions shown
in red, to assist those planning multislit spectroscopy.
For the two inner fields the
exposure were 2 orbits long. For the other flanking fields, the
exposures were 1 orbit. All flanking field exposures are in
Field Selection Criteria
The field is optimally placed in the Northern Continuous Viewing Zone
(CVZ). This fixed the declination to be near +62 deg. The northern
hemisphere was chosen to allow for follow up observations from the
VLA, Keck, and KPNO observatories, although the desirability of
selecting a second field in the southern CVZ is acknowledged should
this be possible in the future.
The position of HDF is shown as a 1 on the attached
IRAS map, and is outlined on the attached
Digitized Sky Survey image.
The HDF is several degrees away from any bright star (>2 deg from
stars <2 mag).
The field is devoid of bright nearby galaxies, stars, known nearby
clusters, and bright radio sources.
The field has low infrared cirrus flux, as judged from IRAS maps,
low extinction (E(B-V) = 0.00),
low hydrogen column density (log(N_H) = 20.24).
