The SDSS imaging camera took its first science quality data the night of September 19, 1998, and was the world’s most productive wide-field imaging facility until its last night of science quality data on November 18, 2009. In between it took a total of around 35,000 square degrees of images, covering a unique footprint of 14,055 square degrees of sky.

Data Release 18 does not include any new or updated SDSS imaging data. To access the imaging data, you can use SkyServer, CasJobs and the Science Archive Server. More information on how to use these data servers, how to work with the data, descriptions of the data formats as well as tutorials and caveats, please visit the Data Release 17 imaging pages on the SDSS-IV website.
