VIXEN "REGULAR" MOTOR AND REDUCTORS

I use the regular motor from vixen, called the MT1. The reduction is a bit to "big", but you get fine tracking without the painfull microstep optimization !

And also a very old computer is sufficient to drive it with the accuracy needed by CCD images.

Note you can find the motor and reductor specification at http://www.pulsemotor-usa.com/PFGHSpecs.cfm?id=4

The unipolar 6 leads 4 phases step motor has 48 step per turn, it is connected to a 1:120 reductor who drives the 1:144 reduction of fine machined worm drive.

So one turn of the scope is 144*120*48 steps, and for RA and DEC axes are the same, and you must use :

AltFullStepSizeArcsec 1.562500
AzFullStepSizeArcsec 1.562500
