ばならないという欠点がある０また。After that, the celestial object is tracked by a tracking device, and the tracking device uses the tracking device to track the celestial object at a speed that the astronomical telescope rotates around its rotation axis exactly once in one sidereal day. When introducing a dark celestial object, the object is introduced into the field of view using a finder, etc., but there is a drawback that the introduction time varies greatly depending on the skill level of the observer, and the tracking device The tracking speed of is also a constant value on the same rotation axis, but the sensitive layer also changes, so fine-tune the right ascension and declination values of the optical axis direction of the astronomical telescope at regular intervals. , 0 also has the disadvantage of having to be done.
さらに追尾装置を駆動する直流モータの回転速度を電圧
にエフ制御しているので、その電圧の変動によって追尾
装置の回転速度が変化するという欠点がある。Furthermore, since the rotational speed of the DC motor that drives the tracking device is controlled by voltage, there is a drawback that the rotational speed of the tracking device changes due to fluctuations in the voltage.

(longitude and latitude) and its correction, as well as time and its correction. The processing unit 2 calculates the azimuth and altitude f of the celestial object to be observed based on the input data, displays this on the calculation display unit, and also controls the right ascension axis control unit 3 and the declination axis control unit 4, the information on the calculation results is sent. The right ascension axis control unit 3 and the declination axis control unit 4, which have received information on the calculation results, respectively control the current direction and the direction of the right ascension and declination axes of the astronomical telescope (i.e., the direction of the celestial object to be observed). ), calculates all the rotation directions and rotation angles of those axes, sends digital pulses to the right ascension axis drive unit 5 and declination axis drive unit 7, and sends digital pulses to the right ascension axis drive unit 5 and declination axis drive unit 7. The pulse motor provided in each is activated to introduce the celestial object to be observed into the field of view.
動的に観測対象の天体を追尾することができる。It is possible to dynamically track celestial objects to be observed.

In addition, if the amount of input data increases and the processing method in the processing unit is changed, the position of the planet January on the celestial sphere will change in a short period of time.
It also becomes possible to perform automatic tracking of stars, etc. over a long period of time.
