Gakken Adult Science Magazine BEST SELECTION01 Pinhole Planetarium Q700240

A planetarium that fills the room with a star-filled sky filled with the Milky Way! The Milky Way is reflected in a collection of tens of thousands of small stars! Stars up to 7th magnitude, which are invisible to the naked eye, are reproduced. The Milky Way is also represented by small dots of light, allowing you to enjoy the sky full of stars as if they were falling down. You can show the starry sky at any place, any day, any time you like! By setting the latitude of the area where you live and adjusting the date and time, you can project the starry sky on the day and time you want to see (Japan area only). ▼A regular dodecahedral star sphere that can project to below the horizon! A regular dodecahedral star sphere corresponds to a celestial body with each side divided into 12 parts. Light passes through everything except the bottom, so even stars below the horizon are reflected. ▼Pinhole type that expresses each star one by one! It is a pinhole type in which the light emitted from the central light source passes through the hole (transparent part in this kit) corresponding to the star opened in the star plate and is projected directly onto the wall or ceiling. The brightness of the star is expressed by the size of the hole. ▼ Supervised by planetarium creator Takayuki Ohira! Takayuki Ohira, who developed the world's most advanced planetarium "MEGASTAR", supervised the kit. Mr. Ohira's stellar data is plotted on the star plate, and the Milky Way and constellations are accurately reproduced. *Uses two AA alkaline batteries (sold separately).
