Zeiss projector

A Zeiss projector is one of a line of planetarium projectors manufactured by the Carl Zeiss Company.

The first modern planetarium projectors were designed and built in 1924 by the Zeiss Works of Jena, Germany in 1924.[1] Zeiss projectors are designed to sit in the middle of a dark, dome-covered room and project an accurate image of the stars and other astronomical objects on the dome. They are generally large, complicated, and imposing machines.

The first Zeiss Mark I projector (the first planetarium projector in the world) was installed in the Deutsches Museum in Munich in August, 1923.[2] It possessed a distinctive appearance, with a single sphere of projection lenses supported above a large, angled "planet cage". Marks II through VI were similar in appearance, using two spheres of star projectors separated along a central axis that contained projectors for the planets. Beginning with Mark VII, the central axis was eliminated and the two spheres were merged into a single, egg-shaped projection unit.

History of development and production

The Mark I was created in 1923–1924 and was the world's first modern planetarium projector.[2] The Mark II was developed during the 1930s by Carl Zeiss AG in Jena. Following WWII division of Germany and the founding of Carl Zeiss (West Germany) in Oberkochen (while the original Jena plant was located in East Germany), each factory developed its own line of projectors.[3].[3]

Marks III – VI were developed in Oberkochen (West Germany) from 1957–1989. Meanwhile, the East German facility in Jena developed the ZKP projector line.[3] The Mark VII was developed in 1993 and was the first joint project of the two Zeiss factories following German reunification.[3]

As of 2011, Zeiss currently manufactures three main models of planetarium projectors. The flagship Universarium models continue the "Mark" model designation and use a single "starball" design, where the fixed stars are projected from a single egg-shaped projector, and moving objects such as planets have their own independent projectors or are projected using a full-dome digital projection system. The Starmaster line of projectors are designed for smaller domes than the Universarium, but also use the single starball design. The Skymaster ZKP projectors are designed for the smallest domes and use a "dumbbell" design similar to the Mark II-VI projectors, where two smaller starballs for the northern and southern hemispheres are connected by a truss containing projectors for planets and other moving objects.[4]

Partial list of planetariums that have featured a Zeiss projector

Between 1923 and 2011, Zeiss manufactured a total of 631 projectors.[5] Therefore, the following table is highly incomplete.

Adler Planetarium

The Adler Planetarium is a public museum dedicated to the study of astronomy and astrophysics. It was founded in 1930 by Chicago business leader Max Adler. It is located on the northeast tip of Northerly Island at the shore of Lake Michigan in Chicago, Illinois. The Adler was the first planetarium in the United States and is part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Adler's mission is to inspire exploration and understanding of the universe.

The Adler Planetarium opened to the public on May 12, 1930. For its design, architect Ernest A. Grunsfeld, Jr. was awarded the gold medal of the Chicago chapter of the American Institute of Architects in 1931. It was declared a National Historic Landmark in 1987.The Adler is home to three full size theaters, extensive space science exhibitions, and a significant collection of antique scientific instruments and print materials. In addition, the Adler boasts the Doane Observatory, one of the only research-active, public urban observatories.

Outdoor sculptures at the planetarium include Spiral Galaxy by John David Mooney, Man Enters the Cosmos by Henry Moore, and America's Courtyard by Ary Perez and Denise Milan.

Bangkok Planetarium

The Bangkok Planetarium is the oldest planetarium in Thailand and Southeast Asia. It is located on Sukhumvit Road in Bangkok as part of the Science Centre for Education, which is operated by the Department of Non-Formal Education of the Ministry of Education.

Construction of the planetarium began in 1962 with a budget of twelve million baht and it opened on 18 August 1964. The planetarium dome is 20.60 metres in diameter and 13 metres high, and holds 450 seats. The planetarium uses a Mark IV Zeiss projector, which was the first installation of a large planetarium projector in Southeast Asia. Apart from the theatre itself, the building also features permanent exhibitions on astronomy, aimed at young audiences.The planetarium underwent extensive renovations in 2015, including the installation of two new Christie Boxer 4K30 projectors alongside the old Mark IV, which helped reignite interest in the previously ailing museum.

Morehead Planetarium and Science Center

Morehead Planetarium and Science Center is located on the campus of the University of North Carolina at Chapel Hill. It is one of the oldest and largest planetariums in the United States having welcomed more than 7 million visitors by its 60th anniversary in 2009. As a unit of the university, Morehead receives about one-third of its funding through state sources, one-third through ticket and gift sales, and one-third through gifts and grants.

First opened in 1949, the planetarium was used to train Gemini and Apollo program astronauts in celestial navigation. Until the late 1990s, it contained one of the largest working Copernican orreries in the world. The facility was donated to the university by alumnus John Motley Morehead III who invested more than $3 million in the facility.

Oswald Thomas

Oswald Thomas (born July 27, 1882 in Kronstadt [now Braşov in Transylvania, Romania]; died Feb. 13, 1963 in Vienna, Austria), was a German astronomer and a protagonist of the popularization of astronomy in Germany and Austria.

Planetarium

A planetarium (plural planetaria or planetariums) is a theatre built primarily for presenting educational and entertaining shows about astronomy and the night sky, or for training in celestial navigation.A dominant feature of most planetaria is the large dome-shaped projection screen onto which scenes of stars, planets, and other celestial objects can be made to appear and move realistically to simulate the complex 'motions of the heavens'. The celestial scenes can be created using a wide variety of technologies, for example precision-engineered 'star balls' that combine optical and electro-mechanical technology, slide projector, video and fulldome projector systems, and lasers. Whatever technologies are used, the objective is normally to link them together to simulate an accurate relative motion of the sky. Typical systems can be set to simulate the sky at any point in time, past or present, and often to depict the night sky as it would appear from any point of latitude on Earth.

Planetariums range in size from the 37 meter dome in St. Petersburg, Russia (called “Planetarium No 1”) to three-meter inflatable portable domes where attendees sit on the floor. The largest planetarium in the Western Hemisphere is the Jennifer Chalsty Planetarium at Liberty Science Center in New Jersey (27 meters in diameter). The Birla Planetarium in Kolkata, India is the largest by seating capacity (630 seats). Thereafter, the China Science and Technology Museum Planetarium in Beijing, China has the largest seating capacity (442 seats). In North America, the Hayden Planetarium at the American Museum of Natural History in New York City has the greatest number of seats (423).

The term planetarium is sometimes used generically to describe other devices which illustrate the solar system, such as a computer simulation or an orrery. Planetarium software refers to a software application that renders a three-dimensional image of the sky onto a two-dimensional computer screen. The term planetarian is used to describe a member of the professional staff of a planetarium.

Planetarium Jena

The Zeiss-Planetarium in Jena, Germany is the oldest continuously operating planetarium in the world. It was opened on July 18, 1926. The Zeiss-Planetarium is a projection planetarium. The planets and fixed stars are projected onto the inner surface of a white cupola.

The Zeiss-Planetarium is owned and operated by the Ernst-Abbe-Stiftung.

It was engineered by German engineer Walther Bauersfeld.

The Planetarium of Nantes open since the June 18th, 1981, aims to present shows to astronomy, for all audiences.

Planetarium projector

A planetarium projector is a device used to project images of celestial objects onto the dome in a planetarium.

The first modern planetarium projectors were designed and built by the Carl Zeiss Jena company in Germany between 1923 and 1925, and have since grown more complex. Smaller projectors include a set of fixed stars, Sun, Moon, and planets, and various nebulae. Larger machines also include comets and a far greater selection of stars. Additional projectors can be added to show twilight around the outside of the screen (complete with city or country scenes) as well as the Milky Way. Still others add coordinate lines and constellations, photographic slides, laser displays, and other images. The OMNIMAX movie system (now known as IMAX Dome) was originally designed to operate on planetarium screens.

Companies that make (or have made) planetarium projectors include Carl Zeiss Jena (Germany), Spitz (US), Goto and Minolta (Japan), Evans & Sutherland (US), Emerald planetariums (Israel) and Ohira Tech (Japan).

Zeiss Major Planetarium

The Zeiss Major Planetarium (German Zeiss-Großplanetarium) is a planetarium in Berlin and one of the largest modern stellar theatres in Europe. It was opened in 1987 on the borders of the Ernst-Thälmann-Park housing estates in the Prenzlauer Berg locality of Berlin.

Planning for the area commenced with old gas works to be torn down by 1981. The 750 anniversary of Berlin gave an opportunity to the communist government to create a new style of housing estates with decorative high-rise residential buildings, a cultural centre with restaurants and a planetarium supposed to be larger than the old one in the Archenhold Observatory of Berlin. The building from architect Erhardt Gißke was opened on schedule on 9 October 1987. The dome of the main hall has a diameter of 23 metres (75 ft) and it is currently equipped with a Universarium IX planetarium projector from Carl Zeiss AG.

The building is not only used for astronomy shows but the dome hall with 292 seats allows also for music concerts and audio drama with the regular "audio theatre under a starry sky" (German: Hörspielkino unterm Sternenhimmel) running since 1995. There is also a café and a movie theatre with 160 seats. The dome hall has not only a planetarium projector but as much as 100 slide projectors, a laser show installation and sound equipment including a recording studio to create new shows. The planetarium has 90,000 visitors every year.
