which stepper and gearbox?
Been doing a bit of reading but a little unsure!
I have a dob driver set up wich i'm looking at fitting and i am chasing stepper motors for it.I know that i need a 1.8deg and 12v but looking at rs aust web site i dont know about the mNm torque.
There is 70nNm, 260mNm 500mNm and higher torques but i figure it would be one of these three.
Does anyone know which one ? Or do i only need a stronger torque just to drive the az.

Also would i need a 50:1 gearbox, or would a 100:1 be better considering i dont half step the motor?
Any help would be much apreciated.
