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. If you
