This research was pursued in a telescope motion control system that leads to right ascension and declination. This research will discuss and create a new system for telescopes that use the ATMega2560 microcontroller which is embedded in the Arduino Mega board as the brain of this system. The way this system works is first the ATmega2560 microcontroller will read the first position of the telescope after that the telescope will be moved by the hand box towards right ascension or declination and then the last position of the telescope will be read by the microcontroller. By using this latest system, the servo motor in the GOTO telescope can move with three-speed modes namely guide, set and slew where the speed of the guide requires a frequency of 1604 Hz, the speed of the set requires a frequency of 51.340 Hz and the slew speed requires a frequency of 501,368 KHz.
