Most people who want to try stargazing have no idea where to start looking. Astronomy apps require you to already know what you're looking for, and generic sky guides don't account for your specific location, time zone, or the current season. The result is a lot of standing outside in the dark, looking up, and giving up.

The whats_visible skill returns a location-specific list of what is currently above the horizon — planets, bright stars, constellations, and notable deep-sky objects — with altitude, azimuth, and rising and setting times. Combined with moon_phase, you know whether the moonlight will wash out fainter objects before you even step outside.

Beginners looking for their first guided sky session, astronomy club members planning observation nights, and science teachers building outdoor classroom activities all use this to get the right starting point for a night of observation.
