The invention relates to astronomy training devices, namely, devices for observing the starry sky.

The purpose of the invention is to expand the demonstration capabilities by providing a simulation of the operation of the telescope.

The drawing shows the training device, a general view.

The astronomy training device contains a spherical map of 1 starry sky, an optical system for. observing its sections, having a gimbal 2, a housing 3 with an end opening 4 for observing and an opening 5 in the side wall for supplying a light flux of a light source (not shown) to the optical system located in area 1 of the map load 6, magnet 7 and a rod 8 rigidly connected to the magnet 7 and the gimbal 2, located in the direction of the azimuthal axis of the card. The axis 9 of the gimbal 2 is perpendicular to the azimuthal axis, and the point of intersection is in the center of sphere 1. At the same time, the optical system is designed as fixed in the end hole 4 of housing 3 with its one end and facing the sphere 1 with the other end of the hollow cylinder 10 having lenses 11 and 12 mounted on its ends, a side opening 13 opposite the opening 5 in the side wall of the housing 3 and a mirror 14 located in the cylinder 10 of one axis with the side openings 5 and 13 of the housing 3 and the cylinder 10. Side opening 5 and 13 are closed frosted glass.

Training device works as follows.

Consider a spherical map of 1 starry sky, the observer sees only a part of it. From a draw cylinder

located on one (q: n with 5 g louvers), KOTophJe are closed with flexible glass. 1 hp F-iy, 1 Il.

rum 10. The spherical map 1 retains its given orientation in space (in azimuth due to the interaction of the magnet with the Earth’s magnetic field; in tangent due to the displacement of the center of gravity).

Cargo 6 is placed in such a way that the center of gravity of the system of gimbal suspension 2 and sphere 1 is on the continuation of the azimuthal axis and does not coincide with the center of sphere 1, and the magnetic axis of the magnet 7 is perpendicular to the azimuthal axis. Therefore, when the direction of the instrument axis changes, which coincides with the axis of the cylinder 10, the necessary parts of the starry map 1 will be opened to the observer.

The Northern, Equatorial, and a part of the Southern sky (except its polar region) can be observed in the device. To view the sky south of the ecliptic, it is necessary to direct the axis of the instrument below the horizon line.

Turning 360 across the countries of the world and tilting the instrument in latitude from zenith to the horizon and below, the observer gets the full illusion of working with a real telescope, and the degree of detail of the sky map can be greater than that available to an unarmed observer. This increases the consistency of observations of the starry sky, reflects the specifics of astronomical observations, and increases the demonstration capabilities of the instrument.
