WD-17S is the first harmonic drive mount based on Servo Direct Drive technology. It has only single stage reducer – backlash less strain wave reducer, and eliminate the transmission/assembly error from belt/planetary gear solution. That’s why we called “harmonic drive” mount, providing high precision guiding performance to you.
The mount weighs 4.3kg and carries telescopes up to 13.5kg without a counterweight. With the counterweight and counterweight rod (optional with M12 thread) the mount can also carry telescopes weighing up to 20 kg.
Optimize base can be smoothly fine adjusted with CNC fine tooth screw and gap control design, which make it much easier for polar alignment.

Controller bracket for use with MBF-1

The MBA-5 bracket is for the control head of the IC-2730E. The MBA-5 does have holes for direct mounting to a surface. Alternatively, the MBA-5 can be held by the MBF-1 base.

Please note that the MBF-1 suction mounting base is sold separately.
