		The Miami Planetarium opened its doors to the public on November 4, 1966 and has entertained and educated children of all ages about astronomy and the wonders of the night sky ever since.
		The Planetarium, home to Jack Horkheimer’s Star Gazer, the world’s first and only weekly television series on naked-eye astronomy, houses a 65-foot diameter domed projection screen with 231 seats.
		At the heart of the Planetarium is a SPITZ “Space Transit Planetarium” star projector, which is capable of accurately reproducing the stars and planets as seen from anywhere on Earth at any time during the year.

		A planetarium is a domed theater in which a realistic and scientifically-accurate simulation of the night sky is created, using a highly-specialized "star projector." With this projector, the movement and relative positions of the Sun, the Moon, and the five naked-eye planets can also be shown against the stars.
		In most cases, the star projector can be rotated about several different axes of motion, giving a planetarium the ability to show the correct sky for any date of the year and any location on the surface of the Earth.
		The Planetarium's main instrument - the large star projector at the center of the theater - is 13 feet (4 meters) long, weighing approximately 5000 pounds (2300 kg), and projects a field of 3800 stars.

		A planetarium is a building inside which a special projector projects (shows) a picture of the sky onto a rounded ceiling.
		This projector works in much the same way a movie projector or a slide projector works, but is more complicated.
		A planetarium projector (also called a planetarium) is over 12 feet (4 m) high.

	Children's museum plan protested
		But a group of protesters, led by former planetarium employee Glenn Walsh of Mt. Lebanon, is opposed to the public funding unless the Children's Museum restores and reuses two historic pieces of equipment from the old Buhl.
		One is a Zeiss II projector that for years was used to display the stars and planets on the domed ceiling of the "Theater of the Stars." The other is a 10-inch refractor telescope once used to study the sun.
		He said the Zeiss projector could remain stored under the floor until a new use is found for it, or could be transferred to the science center as an exhibit.

		The 1972 star projector in UCLA’s planetarium is unlikely to be replaced in the near future despite two decades of attempts to secure funding for a new one.
		The current projector, a discontinued model, is the third projector in the planetarium's history.
		The planetarium was shut down completely in 1992 because the department lacked the resources to maintain the antiquated equipment, which had ceased to function.

		When the Planetarium opened in 1952, it was only the seventh large planetarium in the entire United States and the only one that used a star projector designed and built domestically.
		The opening of the new planetarium, with it's American-made projector made national news, coming at a time of growing interest in space exploration, but before NASA launches were common or man had walked on the Moon.
		Planetariums were so novel in 1952 that some early audience members would call the box office prior to their visit to ask if the evening's show would be cancelled due to fog.

		One method is to run a screw through the bottom of the turntable to the rod; if the enter of the turntable is hollow, then you may need to duct tape the battery assembly to the turntable or mount a piece of thin plywood on top of the turntable.
		The last step for the basic projector is to mount the turntable bottom on a piece of plywood, and then attach this via a hinge to a base.
		When using the projector in the dome, the projector should be mounted at the center of the sphere, at the height of the top of the base ring.

	HISTORIC EQUIPMENT AND ARTIFACTS TO BE PRESERVED:
		This projector, purchased in 1938, was specifically designed to operate in a planetarium theater with a 65-foot diameter dome.
		Buhl Planetarium's Zeiss II Projector was the first planetarium projector in the world to be placed on an elevator, a fairly unique, "worm-gear" elevator built by the Westinghouse Electric Corporation.
		While the rest of the Buhl Planetarium building is both heated and air-conditioned[the Buhl Planetarium building was the first public building in the City(and, possibly the State) to be air-conditioned, when it opened in 1939], this is not the case for the third floor.

		The Planetarium came to be built in Schull due to the largesse of the late Herr Josef Menke, a German industrialist with a keen interest in astronomy.
		The Planetarium is centred around the Carl Zeiss single sphere sky projector, which is capable of projecting an accurate representation of the night sky, from anywhere in the northern hemisphere onto the Planetarium's 8 metre dome.
		The Planetarium is part of the local Community College, and along with the Fastnet Marine and Outdoor Education Centre, provides a unique educational resource to local children.

		The planetarium projector displays the stars visible to the unaided eye from the southern hemisphere, and simulates the apparent motion of the stars as the Earth rotates.
		Planetarium staff are also happy to provide information for teachers who wish to make astronomy a classroom topic.
		A modern planetarium uses not only the main projector but also a variety of equipment including a high-quality sound system, slide projectors and special effects projectors.

		The Springfield projector is not really a "planetarium." It is a stellarium, which can only show the movement of stars; it cannot display the much more complex movements of the planets.
		And, it is the LAST operable planetarium projector from the dawn of the planetarium age.
		We, respectfully, ask that any lease granted to the Children's Museum include a clause that requires the Zeiss II Planetarium Projector and the 10-inch Siderostat-type Refractor Telescope to remain in their original installations, where they can be used.

	Geodesic Domes and Charts of the Heavens
		Early in the 18th century, a fine mechanical planetarium was built by John Rowley for Charles Boyle, fourth earl of Orrery.
		By means of suitable mechanisms the projectors would be moved and guided so that their illuminated images of the heavenly bodies would conform on the dome to the motions which actually occur in nature...
		The projectors are arranged in the centers of the pentagons and hexagons and produce 32 starfields on the same dome.
