8A35.10 - Celestial Sphere
No preparation necessary. 12, 16, and 30 inch celestial spheres are available. The ecliptic and celestial planes are painted on the 12 inch globes with fluorescent paint and may have to be touched up occasionally. The longitude and latitude lines are drawn on the 12 inch globes with permanent overhead projector pens and may also need to be touched up occasionally.
Colored tape was used on the larger two globes for the ecliptic and celestial plane lines.
