Hi! I've read somewhere that servo motors would be much better than stepper motors for astronomical mounts, because of the very philosophy by which they are built: instead of advancing in discrete steps (making it very costly to reduce step-size), they advance at a continuous rate (which is supposedly cheaper to do slowly). Furthermore, I guess in the same article, I'm sure I've read that if you use a pulley and belt system in place of the standard worm gear system (i.e. Harley Davidson motorcycle transmission vs BMW) you are almost sure of eliminating periodic error and all the other irregularities in your drive system.
Has anybody else seen/heard anything like that?
Thanks
Antonio
