1 shows an example of a conventional celestial sphere.

A general conventional celestial sphere 10 has a shape similar to a globe, and has a sphere 11 shaped as a celestial sphere, a rotation shaft 14 and a rotation support portion 12 rotatably supporting the sphere while penetrating through the celestial pole north and south poles of the sphere. And a pedestal 13 connected to the rotary support.

On the surface of the sphere 11, a plurality of constellations 15 images are displayed, and the celestial equator and other right ascension and declination information are displayed.

The user can confirm the constellation position on the celestial sphere by checking the ascension / declination of the constellation of the celestial sphere, and can check the relative positions of the various constellations on the celestial sphere by rotating the celestial sphere.

However, the conventional celestial sphere is a structure that rotates around the north and south poles of the celestial sphere, which is an extension of the Earth's rotation axis, but the relative positions of the constellations can be identified. Since it changes according to the conventional celestial sphere, there is a disadvantage that it is difficult to intuitively know which constellations the observer of a particular place and date can observe.

In other words, the constellation observed by a particular observer not only changes its position on the celestial sphere according to the circumferential movement caused by the rotation of the earth and the revolving movement of the earth, but also the position of the observer on the earth, ie latitude / longitude and the date of observation. Although it changes with time, the conventional celestial body is not suitable for constellation observation because it cannot express all of these changes.

Accordingly, the present invention is to provide a celestial learning device including a celestial device and the observation hemisphere member that can intuitively know the constellation that can be observed by the observer at a particular place and date and time.

Zenith extends the observer's vertical line and meets the celestial sphere on the horizon, and Nidar means the ceiling and the opposite point on the celestial sphere.

Vertical Circle and Hour Circle are members of the celestial pole and the celestial pole that are perpendicular to the global equator. The vertical and time zones on the celestial sphere have the same meaning only by different standards, and may be used in the same sense only in units of time / angle, right ascension line, longitude line, and the like.

Meridian is a crew that crosses the ceiling, bottom, and celestial poles and Antarctica, and has the same meaning as a crew that extends the observer's longitude line to the celestial sphere.

The celestial horizon, or Celestial Horizon, refers to a member who extends the Earth's horizon and meets the celestial sphere. The Celestial Equator is a member that extends the Earth's equator and meets the celestial sphere.

North and South points (North / South Point) means each of the two points where the meridian and horizon meet, the north and south poles of the celestial sphere, and the tie and bookstores are the east and west of the two points where the celestial horizon and the celestial equator meet. Means each point located in the west.

The Autumnal Equinox Point is the point where the sun meets when the sun moves from the southern hemisphere to the northern hemisphere by orbit, among the two points where the celestial equator and the ecliptic (a member of the solar orbit; angled as the celestial equator and rotation axis).

The celestial arctic altitude is the latitude of the observer.

First, in the first use as a celestial sphere, the constellation shape is projected on the surface of the constellation display puzzle, so that the constellation and the sky zone learning can be performed, and the horizontal coordinate system, which is the coordinate system of the current observer center, can be learned by moving the horizontal ring member.

In addition, the constellation display puzzle is displayed as a right ascension and declination can be used to assemble the equatorial coordinate system after assembling them, and can be rotated around the north and south poles of the celestial sphere can be used to explain the celestial movement.

On the other hand, the celestial learning apparatus according to the present invention can be used as a second purpose for identifying constellations observable at a specific location and observation date and time on the earth, the process will be described below.

First, for use as a second application, the latitude, longitude and observation date of the place where the current observer is located are identified.

Next, the horizontal ring member 140 is moved relative to the semicircular support 130 to specify the horizontal plane of latitude of the place where the observer is located (ie, the circumference formed by the ring portion of the horizontal ring member). Latitude lines LA can be used.

Next, the south center reference line member 160 as shown in FIG. 6 is attached to the central axis of rotation of the celestial sphere, and the celestial sphere 110 is rotated so that the observation date comes to the south center reference line.

Next, the time plate member 150 is rotated with respect to the rotation center axis 170 to adjust 24 hours (24h) to the south center reference line.

Then, by rotating the celestial sphere in a state in which the time plate member 150 is fixed to the celestial sphere, the constellation observed at that time is specified by matching the observation time to the southern center reference line.

That is, the constellation exposed to the celestial sphere of the upper hemisphere of the horizontal ring member 140 in the state up to the operation becomes a constellation that can be observed at the corresponding position and time.

In this state, the constellation display puzzle or display puzzle group containing the polarity of the meridian celestial celestial sphere is remembered after storing the constellations arranged at the bookstores, ties, and southpoints near the horizon made by the horizontal ring member 140, and removing the southern reference line member. Remove and attach to the corresponding position of the transparent hemisphere member 200 for observation.

In this state, the visual field is positioned at the inner center portion of the transparent hemispherical member 200 for observation, and then the inner hemisphere surface of the transparent hemisphere member 200 for observation is constellation indicator puzzle attached to the transparent hemisphere member 200 for observation. The constellations displayed on the inner surface can be seen, and consequently, the constellations and sky conditions observed at the location / temporary can be recognized in the same way as the real sky.

As described above, through each operation in the use process as the second use, the celestial hemisphere observable at a specific position (longitude, latitude) on the earth where the observer is located, and the date and time of observation is shown in the area A of the upper left figure of FIG. Is specified as:

In this state, as shown in the upper right drawing of FIG. 7, the constellation indicator or the group of indicators attached to the observable hemisphere region A is detached from the celestial sphere and attached to the surface of the transparent hemispherical member 200 for observation.

In this state, as shown in the lower view of FIG. 7, when the eye O is placed in the inner central portion of the transparent hemispherical member 200 for observation and the inner hemisphere surface of the transparent hemispherical member 200 for observation is observed, a desired position / It is possible to intuitively recognize constellations and sky conditions observed at one time.

In addition, as a modification of the second use of the astronomical learning apparatus according to the present invention, it is also possible to identify constellations observed at different hardness from the observer's position.

Since the celestial sphere according to the present invention can be manufactured on the basis of Greenwich Observatory having a hardness of 0h, if the desired hardness is determined, the date is calculated after the longitude in the case of Seogyeong, and the operation of the second application is performed. What is necessary is just to calculate previously and to operate the said 2nd use by the said hardness.

Through this, it is possible to intuitively identify the constellation or celestial body actually observed at a certain time and time at any longitude and latitude on the earth.

As described above, using the celestial learning device according to the present invention, there is no need to make a constellation plate for a specific latitude and longitude, and only the scale of the night sky that can be observed at a desired date and time can be observed at any desired time regardless of the location of the earth. You can check in shortened form.

And it can still express the coordinate system expression and the motion of the celestial sphere which can be done by the celestial sphere, and it can improve the effect of celestial learning because the viewer can visually check the actual night sky without having to think that the observer is at the center of the celestial sphere.

In addition, there is an effect that can cause interest and interest in the constellations and saints by using a detachable constellation display puzzle.
