These CrossID tools let you match a list of your own sky objects to objects in SDSS data.
Object CrossID allows you to upload search the database for sky positions and objects with a list of object positions, and returns the SDSS objects which are within a certain radius of those positions. A few simple upload formats are supported.
SkyQuery CrossMatch uses the SkyQuery web services to cross-match your list of objects with SDSS and other astronomical datasets.
Schema Browser shows you what data you can find in the database.
