Celestial Globe, Two‑Sphere Demonstration with Meridian Frame, 12.5" Outer Globe
The CELEST1 Celestial Globe is a two‑sphere teaching model that demonstrates apparent stellar positions as seen from Earth. It features a 4" inner Earth sphere and a 12.5" transparent outer sphere printed with constellations, stars, and a shaded Milky Way. Both spheres rotate independently on a common axle mounted in a graduated meridian frame set to the Earth's axial tilt for accurate demonstration of seasonal sky changes.
