Kapan memakai 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.
