【作用】[Action]

上記構成において、固定装置は二つの機能を持つ。 一つは、極軸と共に接眼部を回転させるための極軸に固定する固定装置であり 、他の一つは本体(完全固定体)に固定し、極軸と別に独立して接眼部を本体側 に固定する固定装置である。 夫々の装置の機能を観測目的に合わせて使用する。 次に上記機能を使用した観測例を説明する。 (1) 極軸と共に接眼部を回転させるため極軸に固定する固定装置を使用し た場合。 (a)写真撮影時、駆動装置(モーター等)を使用して自動追尾し、星 を長時間撮影する際に使用する。 このクーデ式望遠鏡は光路を二枚の反射鏡で極軸上に導いているため 、極軸が回転すると接眼部で見る視野は回転する。 従って、上記装置を使用しないで写真撮影した場合、撮影された写真 は極軸を中心に視野が回転したものになる。 (b)写真撮影の時、撮影対象物に合わせてアングルを決める時、等、 この固定装置を緩めながら好みの位置で固定し、撮影することができる 。 (2) 本体(完全固定体)に固定し、極軸と別に独立して接眼部を本体に固 定する固定装置を使用した場合。 (a)眼視による観測に使用する。 この使用例においては、接眼部に天頂プリズム(90°光路を変換す るアクセサリー)を使用し、接眼鏡(拡大鏡)で観測を行う方法がある 。この場合、観測位置(天頂プリズムに取付けた接眼鏡)が一定(回転 しない)している方が容易であり、これは本装置を使用することにより 初めて可能である。 (b)観測し易い位置に接眼部を位置して固定装置を緩めることにより 行える。 上記の如く本考案はクーデ式望遠鏡の接眼部に回転機構及び固定装置を組み込 み、天体観測を多目的に行わせたものである。 In the above structure, the fixing device has two functions. One is a fixing device that is fixed to the polar axis for rotating the eyepiece along with the polar axis, and the other is fixed to the main body (completely fixed body) and independent of the polar axis. It is a fixing device that fixes the to the body side. Use the function of each device according to the purpose of observation. Next, an observation example using the above function will be described. (1) When using a fixing device that fixes the eyepiece along with the polar axis so that the eyepiece rotates. (A) When taking a picture, use a drive unit (motor, etc.) to automatically track and use it for long-term shooting of stars. Since this coup telescope guides the optical path on the polar axis with two reflectors, the field of view seen by the eyepiece rotates as the polar axis rotates. Therefore, when a photograph is taken without using the above-mentioned device, the photographed picture has a field of view rotated about the polar axis. (B) When taking a picture, when deciding the angle according to the object to be taken, etc., the fixing device can be loosened and fixed at a desired position to take a picture. (2) When using a fixing device that is fixed to the main body (completely fixed body) and fixes the eyepiece to the main body independently of the polar axis. (A) Used for visual observation. In this example of use, there is a method of using a zenith prism (accessory that changes the optical path of 90 °) in the eyepiece and performing observation with an eyepiece (magnifying glass). In this case, it is easier for the observation position (the eyepiece attached to the zenith prism) to be constant (not rotating), and this can only be done by using this device. (B) This can be done by locating the eyepiece at a position where it can be easily observed and loosening the fixing device. As described above, the present invention incorporates a rotating mechanism and a fixing device in the eyepiece of a Coude telescope to allow astronomical observation for multiple purposes.
