DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an astronomical object observing system using a network, and extracts a state of an astronomical object from a current time and a current position from information stored and released in a network, so that an accurate astronomical object can be observed. The present invention relates to a astronomical observing system that can be observed at a high speed, a astronomical terminal for the astronomical object observation system, an astronomical information center, and a recording medium storing an operation program thereof in a computer-readable manner.

[0002]

2. Description of the Related Art Observation of celestial bodies requires specialized knowledge, and it is considered that sufficient astronomical observation is difficult unless the relationship between the state of the celestial sphere and the astronomical observation apparatus is sufficiently understood.

[0003] In the daytime, the sun is the sky, and at night, the moon and stars are called the celestial sphere. The celestial sphere is a positive azimuth from the south to the west, a negative azimuth to the east, and a zenith from the horizon. The number of times you go to is called the elevation angle, and the direction from the zenith to the horizon is called the zenith angle. In addition, the astronomical observation notebook, which is indispensable for astronomical observation, records and records the date and time of observation, the weather, the name of the observer, the name of the observed astronomical object, the purpose of observation, the observed mechanical device, etc. Keep it. Also,
The position of the planet on the date can be confirmed by an ephemeris ephemeris using a scientific chronological table.
It is running in RA / DEC. Declination means that the north pole on the celestial sphere is declination plus 90 degrees, the south pole is declination minus 90 degrees, and the right ascension is eastward, based on the line that the sun crosses during the equinox. One hour is calculated to be 15 degrees, with 360 degrees being 24 hours. The vertical line is represented by an ascension line, the horizontal line is represented by a declination line, the ascension is represented by h, m, s, and the declination is represented by a number of minutes and seconds. For example, the position of the Vega of Kotoza, the weaving princess star of Tanabata, is RA 18:35:15, Declination plus 38
The degree is 44 minutes and 10 seconds and does not change depending on the season or time. The declination and RA are revised every several decades, and the 1975 equinox is currently used.

As objects of celestial bodies, the sun and the moon are easy in appearance, but observing the details requires astronomical telescopes and binoculars. Planets such as Mercury, Venus, Mars, shooting stars, and comets , Star clusters, nebulae, and extragalactic nebulae.

[0005] There are two types of astronomical telescopes, a refraction type using a convex lens as an objective mirror and a reflection type using a concave reflector, and the base on which the telescope tube is mounted is called mounting. There are rituals, each of which is finely adjusted with a fine adjustment device. The equatorial ceremony is such that the cylinder rotates in two directions, the right ascension and the declination. In addition, there are automatic tracking devices that read the position of the star with a scale ring or automatically track the star with a motor, but the equatorial ritual requires polar alignment every time observation is made. Polar axis alignment refers to aligning the polar axis of the equatorial mount with the earth's rotation axis correctly. Also, binoculars may be good for observing the moon or Mars,
Observing the planet is impossible.

In order to observe astronomical objects, an all sky star chart, a standard star chart, and an all sky star chart are used, but they are drawn regardless of the season or time when they are visible. You can know the visible constellations.

[0007]

However, even with the above-mentioned expensive astronomical telescope called the equatorial mount, the position of the constellation to be observed changes with time, and it is not easy to find the desired constellation. Furthermore, astronomically hot news changes every day, so for example,
Even on the starry sky in May 2000, on the 5th, the η Aquarius η meteor shower will be maximal, the β constellation β will be minimal, and the moon will be 04 ° 47 'south of Mars. Even if you know the news and events of the current celestial body such as passing through 3, it is not easy to observe it.

Accordingly, it is an object of the present invention to easily know the news of celestial bodies and to greatly reduce the time required to easily detect and observe the positions of constellations and planets from the news.
