Adult Science Magazine No.01 Pinhole Planetarium

Product Description

The Otona no Kagaku Magazine Masterpiece Furoku Reprint Series #1 is a home-use planetarium that accurately reproduces and projects the positions of tens of thousands of stars. This compact and lightweight device can be placed anywhere in your home, allowing you to search for constellations and view the Milky Way. With a projection angle of 330°, it can project stars below the horizon, giving you the sensation of being enveloped by the starry sky. The projector is equipped with an adjustable function that allows you to set the starry sky for your favorite location, season, and time of day. It is easy to operate with a single switch and is suitable for all ages.

Product Specification

The planetarium uses a dodecahedral star sphere to project stars, with each face divided into 12 parts. All of the surface except for the bottom surface is transparent to light, allowing it to project stars below the horizon. The brightness of each star is expressed by the size of the hole in the pinhole projector. The device is supervised by Mr. Takayuki Ohira, who developed the world's most advanced planetarium "MEGASTAR". The star board is plotted with Ohira's star data, and the Milky Way and constellations are accurately reproduced. The planetarium operates on two AAA alkaline batteries (sold separately).

Usage

The planetarium comes with a color booklet that explains how to assemble the unit with illustrations. Even an inexperienced user can complete it in about 60 minutes. By setting the latitude of your area and adjusting the date and time, you can project the starry sky of the day and time you want to see (only in Japan).
