Quando usar Celestial Coordinate Systems 3D Explorer
Use this explorer when you need to see how a published RA/Dec position relates to what is actually above your horizon - and skip it when you only want star patterns or the Sun path.
- Classroom demos of why stars rise and set while their RA/Dec stay fixed
- Showing how the celestial pole altitude equals the observer latitude
- Introducing the 23.44 degree obliquity of the ecliptic
This is an educational grid visualization at the J2000 epoch, not a live star catalog or planetarium.
