Description

Technical Field

[0001] This utility model relates to the field of telescope support technology, and in particular to a theodolite. Background Technology

[0002] Theodolites are commonly used supports for astronomical telescopes.

[0003] Theodolites have two axes: a horizontal rotation axis (for adjusting the azimuth) and a vertical pitch axis (for adjusting the elevation). They are simple to operate, allowing for intuitive adjustment of angles up, down, left, and right without polar calibration. This makes them more ergonomic for visual observation, facilitating the judgment of the target object's position. The equipment's simple structure makes it suitable for astronomical visual observation while also being usable for ground-based observations.

[0004] Various types of telescopes are often used in astronomical observation to obtain different observation effects. Currently, there are generally two types of theodolites: one type has a telescope mounted on the top, which can only mount one telescope, and the other type has telescopes mounted on both sides, which can mount two telescopes, but cannot directly mount binoculars, making it inconvenient to use.
