Hello!
I am about to embark on a small project to build a star tracking platform for my camera, and I would greatly appreciate a little help regarding what design to use, as I am not very well versed in electronics. I have done a fair bit of research and it seems that a stepper motor may be my best bet. As I am sure you all know, I need it to turn the threaded rod in my barn door tracker at precisely 1rpm. This could come directly from the motor or through the resultant gearing.
I think what I want is a pre assembled stepper motor driver controller kit? (some come with, some without the motor) but there are various differing voltages etc, like the following:

Am I on the rite path? I am open to whatever would work best, be it a stepper motor or otherwise, so I would love to hear what other people have used and get some advice on what would work best for me. I am based in London UK.
Cheers!
