The HDF and the SDSS
The HDF, rotated to N,E, and the
SDSS image of the HDF field. Try your hand at the
Austrialian or
Hawaiian
clickable maps of redshifts in the HDF.
One SDSS image
The SDSS image,
with the HDF field in the upper right corner: look for the star/galaxy pair.
The SDSS imaging mosaic
10 fields by 6 columns
of the SDSS strip with the HDF field:
the HDF is in the third column from the bottom, just a bit
to the left of center:
the triplet of 2 stars and an elliptical in the lower right corner
of the image above is readily visible.
The area shown here is about 10 sq-degrees. As of May 2003, the
SDSS had covered 5000 sq-degrees of sky.
