I am in the early stages of the design of a telescope mount and I need a control motor. I am hoping to run it on a battery so I think a DC motor is the way to go, but I need to be able to keep the rotation speed extremely constant for photographic purposes.
So, to my question: Does anyone know of a controllor that can maintain a constant speed with a varying (or most likely, decaying) power input into the motor? If you do, is it small enough to be incorporated into a portable telescope mount?
Edit: I am trying to keep it low cost, which is why I am looking at Servo alternates for now.
