WD-17 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.

The small ToupTek 678M offers optimal performance for planetary imaging and driving. Low readout noise, high dynamic range, peak QE >83%, AR protection window and much more!
This camera weighs only 90g and has a 31.8mm barrel! 3840x2160 pixels while the pixel size is 2 μm.

Using a new large aperture lens and CMOS, under the same ambient brightness, the exposure time of the OCAL3.0 electronic collimator is only 1/20 of that of the second-generation electronic collimator. If the light source is too strong, it is recommended to reduce the gain rather than simply reducing the exposure time. Now, new collimators can adjust the telescope's collimation in darker environments.

The clarity of the OCAL3.0 electronic collimator image has been greatly improved. Now you can see clearer primary mirror marks and more reflection information, and it still performs well when equipped with a correction mirror.
