Aladin previewer
allows you to get images of any astronomical fields
from the Aladin image server at CDS (Strasbourg - France)
These images are issued from several surveys (POSI, POSII, SERC,
ESO,2MASS,DENIS).
Images issue from photographic plates
have been digitalized either by the Space Telescope Science Institute (STScI)
and/or by the Centre d'Analyse des Images (CAI/MAMA)
For Aladin previewer,
these images have been compressed in JPEG format (<30Kb).
You can also get them in FITS.
If you want to work on images
with a more powerful tool
the CDS provides an Aladin JAVA interface.
