Hi, I wanted since several days to write this post and show some of the interesting design choices taken in these days.
First at all, initially I was having a choice to use a dc motor with encoder to control the movement of the telescope mount.
Unfortunatelly, I discovered, that my motor was actually a 127 ac motor. I thought about using a drive for this motor in order to manage the speed. But I thought that I am planning to use the telescope mount in camping areas, away from lights. If they are away from lights, normally there is no energy from the electric grid close to power the motor. So, the best option would be to have an option to power the system with 12v.
With this previous design constraint, I found a different motor.
This is a stepper motor with an encoder mounted in it. This is a good option due to the precision that can be obtained. And for the power control. I already have an L298N module that would work with the stepper motor.
Investigating further, actually there is a post that discourages to use the L298N driver with stepper motors. What it is recommended is a Chopper Drive in order to control current instead that the L298N is not possible to control.
The post that I mention is the following one:

I want to make some testing and get some results if I get the control that I expect with the L298N drive.
