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 best seller of the quintuplet series, the FRA500 90mm; It is an instrument suitable for astrophotography.

Thanks to the quintuplet spaced in the air, it provides a flattened field up to 44mm diagonally without the addition of further flatteners/reducers.

Hybrid equatorial mount with harmonic drive in AR and crown with VSF in declination

***Tripod not included

HikMicro Thunder TH35PC Thermal Image Scope has 384 × 288 thermal detector and 748 × 561 OLED monitor, which provides clear image under harsh environment conditions like darkness, fog, smoke, dust, rain, snow, wood, camouflage, etc.
Multi-purpose and extremely versatile.
The replaceable eyepiece provides a quick and easy way to turn the clip-on into a monocle or optic.
Eyepiece and adapters are not included.
