Description

Technical Field

[0001] The utility model relates to the technical field of eyepiece replacement, in particular to a shared telescope facilitating eyepiece replacement. Background Technique

[0002] In many scenic spots, we can see the shared viewing telescopes. A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. By refracting the light passing through the lens or reflecting the light by a concave mirror, the light enters a small hole and converges to form an image, and then is seen through a magnifying eyepiece. Common eyepieces have various size specifications such as 12 mm, 17 mm, 21 mm, etc. The size of the eyepiece is mainly reflected by the differences in its internal structure and design. The larger the eyepiece aperture, the larger the field of view (but also limited by the objective lens aperture), and the smaller the magnification. Conversely, the smaller the eyepiece aperture, the opposite is true. Therefore, the size of the eyepiece will affect the observation effect and experience of the telescope.

[0003] Traditional eyepiece replacement can only be applicable to the replacement of the same size, and different sizes of eyepieces have different sizes, and it is impossible to fit the eyepiece size during replacement.

[0004] Therefore, it is particularly important to design a shared telescope facilitating eyepiece replacement to change the above technical defects and improve the overall practicality. Content of the Utility Model
