[0002] Astronomical telescope lenses are special lenses designed for astronomical observation photography, usually divided into two types: reflective and refracting. They can record the faint light of distant stars and are often used in combination with astronomical telescopes. Photography astronomical telescope lenses generally do not have the aperture, shutter and other devices of ordinary lenses, but are equipped with special sunshades, long-time exposure and other control systems. This is because astronomical photography usually requires long exposure to capture the details of stars and weak light. The protective structure of astronomical telescope lenses is mainly designed to protect the telescope lens from various environmental factors such as dust, moisture, dirt, scratches and accidental collisions.

[0003] Publication No. "CN212009098U" A wide-angle lens with a protective structure comprises an eyepiece barrel, one side of the eyepiece barrel is fixedly connected to an objective barrel, one side of the inside of the eyepiece barrel is installed with an infrared lens, the inside of the objective barrel is fixedly provided with a shock-absorbing pad that fits with the inner wall of the objective barrel, the inside of the shock-absorbing pad is successively installed with a first lens, a second lens and a third lens, an aperture that is clamped with the shock-absorbing pad is provided between the second lens and the third lens, a lens cover is threadedly connected to the outer ring of one side of the objective barrel, a second waterproof ring is fitted to the outer ring of one side of the shock-absorbing pad, and a third waterproof ring is fitted to the outer ring of the other side of the shock-absorbing pad. The beneficial effect of the utility model is that the protective structure with different functions formed by the protective cover, shock-absorbing pad and light-transmitting plate is made, so that the wide-angle lens is not easily broken when it falls, and the service life of the internal lens is increased. At the same time, the surface of the lens barrel will not crack, thereby ensuring the use and appearance of the wide-angle lens.

[0004] Although the above utility model can make the wide-angle lens less likely to break when it falls, and improve the service life of the internal lens, it will also prevent the surface of the lens barrel from cracking, ensuring the use and appearance of the wide-angle lens, but the lens needs to be cleaned manually by the user, and it needs to be operated carefully to avoid scratching the lens surface. Manual cleaning is not only cumbersome, but also requires certain skills and experience, and the cleaning of the lens often depends on the user's attention and time arrangement. If the lens is contaminated and not cleaned for a long time, it will affect the observation effect and even cause permanent damage to the lens. Utility Model Content
