Query Builder Demonstration

This animated demo shows how to build a simple query using OpenSkyQuery. The query will return object IDs and positions for objects that appear in both the Sloan Digital Sky Survey (optical) and the Two Micron All-Sky Survey (infrared). The query searches a specific area of sky (near ra=180, dec=0) for objects brighter than magnitude 20 as seen by the SDSS. This animated demo shows, step-by-step, how to build the query.
