All of the imaging data for SDSS-III DR8 visualized. For the first half of the zoom, you are seeing the calibrated pixels; for the second half, the calibrated catalog.
Construction of the frames involves touching every object in the entire DR8 catalog. The images and video were created with IDL, the SDSS-III photoop system, idlutils, imagemagick and ffmpeg.
The data were taken as part of the SDSS, SDSS-II, and SDSS-III projects, with a 2.5-m Telescope at Apache Point Observatory. For more information see http://sdss3.org/ . Publication credit: David W. Hogg, Michael Blanton, and the SDSS-III Collaboration.
