Welcome to inquire! Contact: Li Yongjie. Theodolite is a mechanical part of industrial theodolite telescope, the telescope can point in different directions. Theodolite has two mutually perpendicular shaft to adjust the azimuth and horizontal telescope height. Such a stand is simple structure, low cost theodolite, mainly with ground-based telescopes (geodesy, bird watching and other uses), if used to observe celestial bodies, since the direction of motion of celestial bodies day week is usually not perpendicular or parallel to the horizon theodolite offer, thus need to turn the two shafts and the speed can be tracked over time transform objects, but the field of view of the other days of experience relative to the target celestial body rotation, unless coupled with offsetting mechanism to rotate the field of view, or not suitable for long exposure astrophotography.
