Hi All,
Does anyone know of a battery-operated stepper motor controller?
I'd like to use one for visual fine motor focus when I don't want to set up the PC, cables etc. Something like the Moonlite or Skywatcher DC motor focus units, but for those of us with stepper motors already attached.
Avalon were thinking about a re-chargeable one, but I don't think it came to anything:

Thanks for any info.
