Abstract

PURPOSE:To continue desired astronomical observation even when an observing condition has changed for the worse, by providing a means for turning relatively a declination axis side housing against a polar axis side sleeve, and a means for adjusting relative position relation in the peripheral direction of a polar axis of a polar axis side housing and the polar axis side sleeve. CONSTITUTION:At the time of a tracking operation of an object star, a right- ascension coarse adjustment clamp 225 is set to a clamped state, and an intermediate sleeve 200 is formed as one body with a polar axis side sleeve 221 and turns relatively with a declination axis side sleeve 231. When a worm 219 is rotated by a motor, the worm 219 turns relatively around a worm wheel 200a of an intermediate sleeve 20, and accordingly, a declination axis side housing 230 to which a motor housing 218 is fixed turns through the declination axis side sleeve 231 around a polar axis A, and the object star is tracked at a prescribed speed. When a position shift against the object start on the way of tracking, the position is corrected by operating a control 316 of an adjusting mechanism 300 and turning relatively the sleeve 221 in the peripheral direction of the polar axis A against a polar axis side housing 220.

(Prior Art and its Problems) Astronomical observation using an astronomical telescope is usually carried out using a polar axis side housing 22 which is connected and supported to a base 21 so as to be movable relative to each other in the elevation direction, and a polar axis side housing 22, as shown in FIG. The declination axis side housing 23 is connected and supported to the polar axis side housing 22 so as to be relatively rotatable in the circumferential direction of A, and the declination axis side housing 23 is connected to the declination axis side housing 23 so as to be relatively rotatable in the circumferential direction of the declination axis B. After mounting and fixing the equatorial mount 2 with the supported mirror holder side housing 24 on a separate tripod l, the lens barrel 31 of the astronomical telescope 3 is attached to the lens barrel holder 25 on the equator m2. This is done by setting the right ascension and declination positions of the astronomical telescope 3 to desired celestial coordinate positions by adjusting the relative positions between the respective housings of the equatorial mount 2. Note that 26 is a delta polar axis telescope used for polar axis alignment, and 27 is a balance weight for balancing the weight with the astronomical telephoto FI3.

Then, the actual celestial body IG! When making measurements, first set the polar axis A parallel to the earth's rotation axis using the polar axis telescope 26,
Next, the equatorial mount 2 is set so that the astronomical telescope 3 is positioned in the desired direction of declination and right ascension, and once the target star is introduced into the field of view of the telescope, the declination is then adjusted in the direction of the diurnal motion of the star. The length of the housing 23 on the shaft side allows tracking and observation of the target star.

By the way, when the rotation of the declination axis side housing 23 to follow the zero motion is automatically operated by a motor or the like, the refractive index fluctuation of light (so-called "atmospheric difference") caused by changes in atmospheric conditions in the observation direction
) or due to the accumulation of speed errors originating from the tracking rotation mechanism itself of the equatorial mount 2, the target star may deviate from the center of the telescope's field of view, and in some cases, the target star that has been introduced after much effort may be lost. In such a case, the automatic tracking rotation by the motor will be temporarily stopped, and the automatic tracking rotation by the motor will be restarted after performing the specified error correction operation, but of course, astronomical observation must be interrupted during this time. When you no longer obtain the target star and spend a considerable amount of time reintroducing the target star,
There may be times when we are forced to abandon continuing observation that night.

In the equatorial mount configured as described above, during the tracking operation of the target star, the right ascension coarse movement clamp 225 is in the tightened state, and the intermediate sleeve 200 is integrated with the polar axis side sleeve 221 and the declination axis side sleeve 231 is in a tightened state. It is in a state of relative rotation. When the worm 219 is rotated by the rotational driving force of a motor (not shown) in a stiff state, the worm 219 is moved to the intermediate sleeve 2 because the intermediate sleeve 200 is in the fixed state 7g.
This results in relative rotation around the worm wheel 200a of 00. Therefore, the declination axis side housing 230, which fixes the motor housing 218, rotates around the polar axis A via the declination axis side sleeve 231, and tracks the target star at a predetermined speed.

That is, when the adjustment screw 312 is turned by the knob 316, the top 311 selectively moves to the left or right in FIG. 2 depending on the direction of rotation. The polar axis side sleeve 221 rotates relative to the polar axis side housing 220. Therefore, as the polar axis side sleeve 221 rotates,
The intermediate sleeve 200 connected to this by the right ascension clamp 225 and the declination axis side housing 230 connected to this intermediate sleeve 200 via a worm gear mechanism simultaneously rotate integrally with the polar axis side sleeve 221.
Therefore, when correcting the positional deviation with the target star, there is no need to cancel the automatic tracking operation by the motor.
