It is therefore desirable to develop an image pick-up device that is convenient and practical for use with an amateur telescope for astronomical observers and natural scene lovers to carry and use it easily. However, since the CMOS (or CCD) camera having high sensitivity is relatively expensive and must be equipped with a cooling means and operated indoors, it is more suitable for use in an astronomical observatory or other similar professional organizations. It has been quite a long time since a complementary metal-oxide semiconductor (CMOS) (or a charged-couple device, CCD) camera was mounted onto an astronomical telescope to take pictures. Such a combination is normally designed for use with a low-power compact binocular, and therefore has an objective lens having relatively short focal length and limited light collecting capability, making it not suitable or practical for use with a high-power telescope designed for long-distance bird watching or astronomical observation to obtain good image quality. In the binocular and digital camera combination, the optical path of the camera and that of the binocular are independent of one another. There has been developed a binocular and digital camera combination to integrate functions of the binocular and the digital camera. 1 shows a conventional high power monocular (telescope or spotting scope) 60 having an eyepiece 61 connected to a rear end thereof, such that images of external objects or scenes at a long distance away may be clearly observed or viewed at the eyepiece 61. To enable keeping of beautiful images through easy operation, it is desirable to improve the existing photographic technologies for users to enjoy photography in a more convenient and economical manner. When a conventional still camera is used to take pictures of favorite objects or scenes, it is also necessary to develop films and print the pictures. To do so, the user has to additionally prepare complicate and valuable photographic equipment and own professional photographic skill. People usually use a telescope to watch birds or observe various heaven objects, and often want to keep any favorite scene as a memorial. The present invention relates to a digital image pick-up device that can be mounted on a high power monocular (spotting scope or telescope) to enable a user to pick up an image of a dynamic or a static object or scene being viewed with the high power monocular (telescope or spotting scope) and store the picked up image in a memory device.
