を捉えたまま追尾できるようになっている。2. Description of the Related Art As a conventional telescope, for example, there is one shown in FIGS. 3 and 4 (Japanese Patent Laid-Open No. 4-2091).
(See No. 4). Reference numeral 1 is an astronomical telescope as a "telescope". As shown in FIG. A guide telescope 5 attached to the upper part and oriented in the same direction as the lens barrel 4, and a support arm 6 for supporting the lens barrel 4.
And a base portion 7 that rotatably supports the support arm 6
It consists of That is, by rotating the lens barrel 4 and the guide telescope 5 with the motor m about the polar axis K, the lens barrel 4 and the guide telescope 5 can be tracked while capturing an observation target in space.

ている。Since the main reflecting mirror 2 and the sub-reflecting mirror 3 are housed in the lens barrel 4 as described above, the light flux reflected by the main reflecting mirror 2 is condensed and strikes the sub-reflecting mirror 3. The sub-reflecting mirror 3 further reflects the light flux so as to pass through the central hole 2a of the main reflecting mirror 2, and the light flux is focused on the focal position on the optical axis A, and then passes through the convex lens L 1 to the eyepiece 8. It's coming.

に観察できるようになっている。Further, two convex lenses L 2 and L 3 are also provided in the guide telescope 5 attached to the upper part of the lens barrel 4, and the light beam introduced into the guide telescope 5 is guided by these two convex lenses. It can be observed from the eyepiece 9 through L 2 and L 3 . In other words, since the guide telescope 5 has a lower magnification than the lens barrel 4, first, while looking through the eyepiece 9 of the guide telescope 5, the vicinity of the observation target is specified with a wide field of view, and then the eyes are attached to the lens barrel. The lens barrel 4 allows the observation object to be observed in detail with a narrow visual field and high magnification.

接眼部８、９を覗くような場合には、上記のように大き
な姿勢の変化が強いられることは安全上好ましいもので
はない。However, in such a conventional technique, since the guide telescope 5 is simply attached to the upper part of the lens barrel 4, the guide tube 5 is attached to the eyepiece 8 of the lens barrel 4. A large distance D was generated between the guide telescope 5 and the eyepiece 9. In particular, recently, as the size of astronomical telescopes has increased, many of those having an effective diameter of the lens barrel 4 of 60 to 100 cm class have been constructed. With such a large astronomical telescope, the distance D is 40 cm or more. Therefore, it is very inconvenient for the observer to look at the eyepiece 9 of the guide telescope 5 and then the eyepiece 8 of the lens barrel 4 because the observer has to change his / her posture greatly. In particular, when sitting on the table and looking through the eyepieces 8 and 9 during nighttime observation when the feet are not clearly visible, or when the children take turns in order at the science museum etc.
When looking into the eyepieces 8 and 9, it is not preferable in terms of safety to force a large change in posture as described above.
【０００６】この発明はこのような従来の技術に着目し

ある。The present invention has been made in view of such a conventional technique, and provides a telescope and a guide telescope in which a large posture change is not forced during observation.

ものである。In order to achieve the above-mentioned object, the telescope according to the present invention is formed by bending the eyepiece side portion of the guide telescope toward the eyepiece side of the lens barrel, The eyepiece of the telescope is made to face the position adjacent to the eyepiece of the lens barrel.

変容易になり便利である。[Function] Since the eyepiece of the guide telescope is in a state of being exposed to the position adjacent to the eyepiece of the lens barrel, the distance between the eyepiece of the guide telescope and the eyepiece of the lens barrel becomes small, The observer can look into both eyepieces without significantly changing the posture. Therefore, it is safe for the observer to ride on the table at night for observation, and the observation by the telescope itself is very easy and convenient.

対の反射鏡Ｍ1 、Ｍ2 が設けられている。In the guide telescope 10 of the astronomical telescope 12 according to this embodiment, the eyepiece side portion 10a is bent in a crank shape toward the eyepiece 8 side of the lens barrel 4, that is, downward. Further, inside the guide telescope 10, a pair of reflecting mirrors M 1 and M 2 for guiding the optical path along the crank bent shape are provided.

ため望遠鏡１２自体の操作性が向上すると共に観察者も
疲れにくくなる。As described above, since the eyepiece portion 10a of the guide telescope 10 is bent downward in a crank shape, the eyepiece portion 11 of the guide telescope 10 is the eyepiece portion of the lens barrel 4. 8 is located immediately above the position adjacent to 8, and the distance d between the eyepiece 8 of the lens barrel 4 and the eyepiece 11 of the guide telescope 10 is very small. Therefore, when the observer looks into the eyepiece 11 of the guide telescope 10 and specifies the observation target with a wide field of view, and then moves the eyes to the eyepiece 8 of the lens barrel 4, the observer only needs to slightly move the head. , It is not necessary to change the posture significantly. Therefore, it is safe when observing on a platform at night, and also when children are sequentially observing on a platform at a science museum. Further, since the moving distance of the eye is small, the operability of the telescope 12 itself is improved and the observer is less likely to get tired.

An example in which a pair of reflecting mirrors M 1 and M 2 is used to change the optical path in 0 has been shown, but the present invention is not limited to this, and another optical element such as a prism may be used. Further, an example has been shown in which the guide telescope 10 is attached to the upper part of the lens barrel 4 and the eyepiece side portion 10a of the guide telescope 10 is bent downward, but the present invention is not limited to this, and the guide telescope 10 can be attached at any position. The side portion of the lens barrel 4 may be either sideways or below. The point is that the eyepiece side portion 10a is bent toward the eyepiece 8 side of the lens barrel 4, and the eyepiece 11 of the guide telescope 10 is the lens barrel. It suffices to face the position adjacent to the eyepiece portion 8 of No. 4. Furthermore, although a large astronomical telescope has been described as an example, a small telescope may be used, and even with such a small telescope, both the eyepieces of the lens barrel and the guide telescope are close to each other, which is convenient for operation, never tired.
