Terminal Configuration and Performance Description
Optical section main technical parameters
One, telescope tube
The astronomical telescope is mainly composed of three systems: the main mirror, the guide telescope, and the star-finding telescope. The optical axes of the three systems are parallel to each other.

Main Technical Parameters of the Mechanical Part
Rack
1. Rack: Equipped with advanced German equatorial mount system, the pedestal and equatorial mount can be disassembled separately, facilitating transportation and installation tuning.
2. Equatorial Mount Dynamic Range:
Equatorial Axis: 0h-24h Declination Axis: ±90
The observed azimuth angle points to a scale with reading indicators.
Section 3: Electric Control Drive System
The equatorial mount's right ascension and declination axes are controlled by a dual-motor dual-servo computer single board program.
(1) The driving speed in the right ascension direction during tracking observation is:
Tracking Speed (Constant Motion) = 15'/minute
(2) The control of the polar axis and the declination axis features three speed settings: rapid search, slow fine adjustment, and micro-motion fine adjustment.
Quick Search: ±(30°-60°)/minute
Slow motion fine adjustment: ±(1°- 3°)/minute
Fine Adjustment: Earth (1)-3 pieces/minute
To ensure that the observer can quickly locate celestial targets and accurately track them.
IV. Automatic Tracking System:
Programmable control system designed according to the different motion trajectories of celestial bodies, automatically drives the main optical path system (main telescope tube) to achieve automated celestial body tracking.
V. Automatic Star Tracking System:
The Automatic Star Finder System is designed as a quick guide for beginners to locate celestial bodies. Its advantages include an operating system with a human-machine dialogue interface, featuring a microcomputer installed in the automatic star-finding control box, controlled manually.
The Chinese star chart on the box, by clicking on celestial bodies in the star chart, automatically finds their coordinates. Use this method to control the telescope, aiming it at the celestial bodies you wish to observe. Simple operations can capture the boundless starry sky.
