After processing the images, lists of observed objects and related parameters are produced. It takes images using a photometric system of five filters (named u, g, r, i, and z). It uses a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The Sloan Digital Sky Survey ( SDSS) is a major multi-spectral imaging and spectroscopic redshift survey. The most surprising fact is that they are all free!
