How do I...

Find images and spectra for all objects in a given RA/Dec/Magnitude/Absolute Magnitude range?


You can use the SDSS search tools to find all objects that meet certain criteria, such as position, magnitude, color, or absolute magnitude. The guide How do I find data for all objects in a given RA/Dec/Magnitude/Absolute Magnitude range? shows how to use SkyServer's search tools to find data.

But in addition to searching for catalog data, you can also search for images and spectra using any constraints you want, including position, magnitude, and absolute magnitude. To search for images and spectra, you will use the Image List tool along with SQL (links open in separate new windows).

This is an extremely powerful way to access SDSS data, because it allows you to search based on any criteria, and then to quickly view all objects that meet your criteria.
