Another question . Would a Nema17 stepper motor be powerful enough to move a EQ platform smoothly. I can imagine a lot more torque would be required to drive a platform rather than a conventional DOB mount ,particularly mine as both my azimuth and altitude bearings are lazy susan and if anything run too freely. Another advantage I could see in a platform would be the possibility of being able to plonk both my telescopes on the same platform and as I am hoping to make a 12 inch mirror next year ,the possibility could arise of being able to use the same platform for all 3? What are peoples thoughts on this?
