Abstract: A star projection device is formed from an opaque film sheet folded to form a six-sided, cubical enclosure, the film having transparent spots extending over its entire area representing star positions when projected onto a surrounding surface, and a small, point-like light source is positioned at the center of the enclosure for projecting light simultaneously through all of its six sides to produce a substantially 360.degree., horizonless projection of the stars onto surrounding surfaces. Nearby stars are represented by linear extensions from the transparent spots representing vectors corresponding to the magnified heliocentric parallax motion of the star.
