Lottery: Baader Planetarium NV 110/220

EDUCATIONAL PLANETARIUM BAADER PLANETARIUM NV 110/220 Prestigious Educational Planetarium.

Useful for demonstrating astronomical phenomena of different kinds and suitable for primary, secondary and even university students.

Its design allows studies to be carried out both from a geocentric and a heliocentric point of view.

WARNING: Given the particular characteristics of this extraordinary planetarium, it is a product that is only manufactured to order and the delivery time is approximately 6 months.

Its manufacture is totally manual and each piece is made with the dedication and care that only BAADER PLANETARIUM is able to offer in its products.

40 YEARS OF BAADER PLANETARIUM NV 110/220 With the intention of demonstrating celestial mechanics interpreted from both the heliocentric and geocentric point of view, a large number of BAADER PLANETARIUM planetariums have demonstrated their scientific capabilities in front of students and amateur astronomers from all over the world.

This planetarium presents an absolutely unique and patented method to demonstrate the relationships between the heavenly bodies.

Description The BAADER PLANETARIUM NV 110/220 planetarium consists of three parts: the semi-sphere with stars that can be black and transparent simultaneously, the Solar System including its motorization system, located inside the sphere, and finally the base that contains the transformer and all the associated control electronics.

The sky globe of the BAADER PLANETARIUM NV 110/220 is made of Plexiglass (R) which has been treated in black to obtain approximately 5% transparency.

This material produces an extraordinary optical effect: with the incidence of direct light, the globe will appear practically opaque due to the absorption and reflection properties of the plexiglass (R).

However, when observing the planetarium in a dark room, the human eye will adapt to the existing light conditions and the sphere will appear transparent: the Solar System inside the globe will be seen clearly.

Using three different colours, the stars and constellations have been printed on the outside of the globe: stars up to magnitude 5 are represented and the constellations are indicated by connecting lines between stars.

An equatorial graduation circle allows the position of the fixed stars to be located, making it easier for the educator/divulgator to explain the principles of astronomical navigation.

By using white paint on the inner side of the globe, the observer has the feeling of actually observing the sky with its white stars on a black background.

The Ecliptic has also been included as a line, indicating the months in the correct order so that the actual position of the Earth can be seen at any time of the year.

The entire globe or sphere can be rotated in all directions and aligned with the apparent position of the sky, clearly demonstrating why at different times of the year there are parts of the sky that we cannot observe.

The Solar System of the BAADER PLANETARIUM NV 110/220 uses a microscope bulb in the centre of the sphere as a light source.

It can be covered with a removable plastic balloon providing a body of diffused light that perfectly represents the Sun.

The planets Mercury, Venus and Mars are shown together with their orbits.

They can be adjusted by hand, to demonstrate their positions during the phenomena of opposition and conjunction.

The outer planets are shown with their orbits printed on the inner side of the globe.

This allows the observer to compare the relative positions and inclinations of the different orbits to the ecliptic plane of the Earth.

The Earth-Moon system is equipped with a miniature variable speed motor.

In this way the following movements can be demonstrated: 1.

The movement of the Earth around the Sun (Translation) 2.

The Earth rotating on its own axis (Rotation) 3.

The Earth's axis pointing towards the celestial poles 4.

The movement of the Moon around the Earth 5.

The movement of the moon nodes.

This mode of representation and the precision achieved constitute a unique combination.

It really facilitates the understanding of many of the relationships established in celestial mechanics: the mechanics and causes that give rise to day and night, the mechanics of the weather stations, the understanding of the movement of the Moon, phases and their eclipses.
