Description

1271543 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a telescope, and more particularly to a focusable image capturing telescope capable of quickly capturing a clear picture on the same day of the telephoto. [Prior Art]

Back to 1 is not a conventional image capturing telescope combining a telescope and a digital camera. Since the telescope simply combines the telescope system 1 and the digital camera system 2, the optical systems of the two do not have any Correlation, the silk world is also different from each other. Because the user uses the telescope system to view distant scenes, the user can not immediately use the digital camera system and system 2 to clearly capture the scenes they see. As a result, users often have to constantly carry out two (four) (four) games. 〃 Figure 2 is not another conventional image capturing telescope that combines a telescope system with a digital camera system. The optical system 3 of such a telescope uses: a spectroscopic 〇3〇3胄 incident from an objective lens. The light is split into two to be projected onto the eyepiece 3G2 for viewing by the user, and the other is projected through a lens 304 to the imaging unit 3〇5 # synchronous shooting. Although: such a telescope can improve the lack of simultaneous viewing and shooting of the telescope, but in practice (4), the telescope has the following missing. The telescope is manually adjusted to perform the objective 301. Tune: The human eye... The eyepiece 302纟 determines whether the scene image being viewed, the moon is clear, ', and 'because the human eye is different from the focusing imaging mechanism of the imaging unit 3() 5, so when the user feels The focus is clear on the same day, not on behalf of 5 1271543. The lens 304 can be like a clear dragon, so it will cause a difference between the viewing and the sharpness of the camera. Watching the LCD screen is supplemented. Secondly, due to the size and resolution limitations of the LCD screen, it is difficult for the user to distinguish whether the focus is clear through the LCD screen, and the method of adjusting the material is difficult to report. Fine focus fine-tuning. So, although this kind of reading can capture the scenes while watching, it will not be able to capture a clear picture due to the problem of focusing. — Figure 3 , 4, for the conventional one and look at the instrument (China invention patent certificate number of the first instrument. Including - right telescope system 4, a left telescope system 5, a = camera system 6, - spectroscope 7, _ mirror state Two gears = stepper motor 9. Although the New Zealand optical viewing instrument can automatically capture a clear picture of the green camera system 6, the user can view the distant scene by the right 'telescope system 4, 5. However, in actual use: This optical viewing instrument has the following drawbacks: First, the digital camera system 6 now, Α 7, the left telescope system 4, 5, a n-eight fine move the right 7 main mirror One of 401, 501, 503 to carry out the line adjustment action, (4) the stepping motor 9 drives the machine = the outer gear of the "gear section 6 () 7, _ _ stomach a guide pin 606 and a cam guide , I & no x A, the second mirror group 6. 3, 6 〇, etc. 74, therefore, in order to make up for the difference between the first - '... 4 objective lens 403, 503 ratio 1271443 The second mirror group 603, 604 moves to a position that causes the impact on the surface of the lens 602. The lens barrel 602 tends to drive the first long distance from the green To be movable in focus imaging efficiency. Two right and left telescope 4,5, since such an optical
