Starmaster PDF Print

Planetarium Projector StarmasterThe Starmaster is a projector of the new generation. It is equipped with fiber optics, and the stars appear significantly brighter and sharper than with its antecessors (Spacemaster and M-1015). Their number is close to 9000. The classical fragmentation into 32 star fields were reduced to 12 wide angle objectives that were specially developed for the dome projection. As in the Universarium type, the starry sky is aggregated on one star ball, but it is illuminated by one light bulb. The planetary projectors are outsourced to an own plattform and can be actuated individually. A special pecularity is the integration of the sun and and moon projectors as cubes on the star ball. This opens the possibility to demonstrate the midsummer sun or the fullmoon at noon without shading effects. This projector can be applied in domes between 12 and 18 meters.

Zeiss ZKP-3The technics of the Skymaster line was improved only after 1992. The effiency was intensified such that domes with 12 meters could be equipped with it. Those features of the larger versions like grids and constellation figures are built it. The first copy was delivered to the 11-m-dome in Pachua, Mexico, in February 1993.

ZKP-2 (Skymaster) PDF Print

ZKP-2, SkymasterThe small facilities could face a new step in the development, when the ZKP-2 entered the market. Basically, it is a smaller version of the Mark-IV or the UPP, respectively. It displays 6000 stars, the planets, lunar phases, and the Milky Way. The latter appears as a whitish zone. The projector is mounted on a pillar and can be illuminated from below. In the 1990ies, the name "Skymaster" was assigned, and it carried over to the next models.

Planetarium Projector ZKP-1The Zeiss Kleinplanetarium (ZKP) was built from 1952 to about 1980 in Jena. It was the only projector for small plantariums for many years, and it turned out a surprisingly robust instrument that is still in use in many facilities around the World. Its design most resembles the first Model-I projector, for the complete sky of the Northern and Southern hemisphere is stored on a single ball. It has 32 lenses, each of which maps approximately 150 stars, so, almost 5000 stars can be shown. Futhermore, it has additional projectors for the Milky Way, the planets and the moon. The handling is purely hand operated, thus, the presenter has to operate it from the center of the dome.

M-1015 (A) PDF Print
Zeiss

Planetarium Projector M-1015It was not until 1980, when Zeiss in West Germany built projectors for the small and medium planetaria. The M 1015 is such a device directed to dome sizes between 10 and 18 meters. It showes 5000 stars till the 6th magnitude as well as a few other stellar objects, e.g. the Andromeda galaxy. The moon exhibits phase changes and surface details. The diurnal and annual motions, the polar height and the precession can be adjusted continuously. The first instrument was given to the William Staerkel planetarium in Champaign (Illinois, USA). In Germany it is presently located in Laupheim, Kassel and the Deutsches Museum in Munich.
