 | | (This planetarium had a 30 meter dome, one of the largest ever constructed, and totally destroyed in the war.) The Model 11 was the large dumbbell-shaped projector which everyone has since identified with Zeiss. |
 | | The Fels Planetarium became the second in the U.S., opening on Nov. 1, 1933, and 1935 saw the opening of the Griffith Planetarium on May 14 and the Hayden Planetarium on October 2. |
 | | The planetarium is school, theater, and cinema in one classroom under the eternal dome of the sky." |
