The simplified observing list includes a What’s Up? query that lets
you specify the viewing time, your optical aid (naked eye, binocular,
or small telescope) and which objects you’re interested in seeing
tonight; TheSkyX’s What Up? command generates a report for you, complete with fascinating descriptions about many deep-space objects, sample photographs of the object (when available), and Hertzsprung-Russell (HR) diagrams for stars.
You can scroll through each object in the report and watch the Sky Chart update to show you exactly where to look for the object.
