Electric focusing device for astronomical telescope with handle

Astronomical focusing device, supporting Ascom and Indi protocols.
(1) 5V power supply, only need to connect the USB interface data cable to the computer, wiring and power supply are simple;
(2) Supports Ascom and indi, and can achieve automatic focusing in NINA, MDL, sharpcap, or kstars. If you do not need to use the above days
Wen software, as well as specially developed control software, can easily control the focusing device through a computer;
(3) Specially customized 35 high torque stepper motor, more finely divided than EAF motor, with 3840 steps per circle, high subdivision degree, and the number of steps in the focusing area is also higher
more.
Regarding the gap (also known as backlash), the gap is mainly generated by the mechanical structure of the focusing seat, and the gap introduced by the focusing device itself can be ignored
Many people do not understand this principle. Empty distance exists as long as it is a mechanical device, and can be offset by setting it in the software. It does not represent the performance of the focusing device
