The Control Circuit of the Telescope for the Observation of Halley's Comet

  • The control circuit of the four-axis telescope, which is used to observe Halley's Comet in Yunnan Province, is introduced in this paper. A CMOS integrated circuit with high anti-interference and lower power consumption is used in the control circuit and a step motor is utilized as the driver. The rotational speed is adjustable and stable, thereby making the mechanical rotation system much simpler.
