PLANISFERIUS. PLANISFERIO MEDIANO
Buscador de estrellas. Para realizar la observación es necesario hacer coincidir el día del mes con la hora girando el disco. Orientando el norte del planisferio con el norte geográfico, la parte del cielo que queda enmarcada por la elipse es la visible en ese momento. 20 cm de diámetro en cartón rígido. Gracias a la tinta fluorescente utilizada, unos segundos de exposición a la luz serán suficientes para hacerlo visible en la oscuridad, de modo que no será necesaria ninguna luz auxiliar para realizar su observación.
Se representan las estrellas y constelaciones visibles alrededor de la latitud 45º Norte.
