The Carl Zeiss Planetarium Projector gets a cameo in THE NIGHT OF THE COMET. This is what it looks like. Kind of creepy, isn’t it?

Zeiss Projector, Adler Planetarium, Chicago

“While the spectators sit comfortably below, as we see them here, the Planetarium, through an electric control board is caused to project upon the overarching vault an amazingly realistic representation of the pageant of the heavens.”
