Hello David,
Coupling the SharpSky motor, or any other motor, depends on several factors. Obviously, the scope focuser design and how handy you happen to be mechanically. If you are considering the upgrade but not too sure about the mechanical aspects I can send you a SharpSky bracket as fitted to the motor.
The bracket is adjustable length ways so once a suitable mounting point has been identified aligning the motor drive with the respective focuser drive shaft should prove relatively straight forward.
Looking at your focuser you appear to have a couple of mounting screw points either side of the knurled lock/tension adjustment. You also have a large flat surface (the blue face) which could be used as a fixing point.
If you would like a bracket in the flesh, so to speak, please let me know
Shaft diameter :
If you let me know the diameter of the focuser drive shaft I can customize the flexible aluminium coupler to any shaft
size equal to or in excess of 3mm.
Cheers & clear skies (wall to wall cloud here),
Dave
