I re-wrote Michael Covington’s software and built a sucesful drive for my old orange tube celestron. Works very well. I’m still using it.My old, now orphan, web page at http://mizat.club24.co.uk/ has details and links to Micheal’s site.I suspect that this will be overkill for this application. It pulls nearly 1 amp at 12 volts. Unless driven from a car’s battery the total result including a battery pack would be far from portable. I took a similar arrangement cobbled together from bits of my home telescopes to an eclipse in Africa in the 70’s and given that it only had to work for a few minutes a 12v stack of D cells worked OK. They didn’t XRay luggage at the airport in those days otherwise I would probably still be in jail today as the resutant stack looked just like the bundle of dynamite sticks that often featured in the cowboy films of my childhood!Roy
