http://stdatu.stsci.edu/cgi-bin/dss_form The Space Telescope Science Institute hosts the Digitized Sky Survey
, an online archive of scanned images from the Palomar Sky Survey, ESO Quick-Blue Survey, etc.
The 1-trillion-pixel view seamlessly stitches together thousands of images from the Digitized Sky Survey
, an all-sky photographic atlas.
X-ray observations from Chandra and XMM-Newton have been combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey
Users can select objects according to apparent magnitude and download their images from the Digitized Sky Survey
. (You can combine different filters to show a color image.) For each object, you'll find information such as its sky coordinates (RA, Dec), size, magnitude, surface brightness, and rise and set times.
The stellar stream in NGC 4449 was first detected by another group of astronomers as a mysterious, faint smudge in digitized photographic plates from the Digitized Sky Survey
project, and it is also visible in archival images from the Sloan Digital Sky Survey.
The ones in this article were generated by combining the red and blue POSS-II plates from the Digitized Sky Survey
(DSS); similar results can be obtained from WikiSky or the Aladin Sky Atlas.
An essential resource for really-deep-sky observers is the Digitized Sky Survey
(DSS), based on the Palomar Observatory Sky Surveys.
The third tab is Footprints, which brings up an interactive display of the various fields of each instrument data set overlaid on a Digitized Sky Survey
(DSS) color composite of the imaged area.
The Plus version of the program ups this to about 2 1/2 million stars to 12th magnitude, 30,000 deep-sky objects (including the entire NGC and IC catalogs), about 300 images from the Digitized Sky Survey
, and roughly 1,000 object descriptions.
