The Deep Sky Project
Deep Sky is an astronomical image database of unprecedented depth, temporal breadth, and sky coverage. Image data are gathered from the Near Earth Asteroid Tracking (NEAT) project from the 3-CCD and Quest 112-CCD cameras on the Samuel Oschin telescope at the Palomar Observatory in San Diego County, California. Containing a total of eleven million images, or 70 terabytes of image data, Deep Sky covers nearly the entire northern sky.

Deep Sky images cover:
  • 20,000 square degrees,
  • one decade of temporal coverage, consisting of eleven pointings on average
    at any given set of sky coordinates,
  • image depth an order of magnitude greater than most other large sky surveys.

The form below allows for sub-selection of Deep Sky data in terms of location in the sky, date/time, and by instrument. The location in the sky is defined in terms of right acension (RA) and declination (DEC) which are similar to longitude and latitude. For some help getting started, try some of the interesting places in the sky listed in the upper left corner under "RA/DEC suggestions."
