Precision Forged in Myth. Built for the Stars.
Named after the Norse god of law, justice, and unwavering resolve, the Týr Mount delivers unmatched accuracy in celestial tracking — a harmonic drive telescope mount engineered for serious astrophotographers and observatories who demand absolute precision.
Týr is not the god of chaos. He is the god of control.
And in the same spirit, the Týr Mount locks onto the heavens with unshakable intent — guiding your optics with sub-arcsecond accuracy, even across long exposures and complex sky paths.
Engineering Highlights
- Geared for unparalleled Precision: With a gearing reduction of 750:1 on the RA and 400:1 on the DEC axis, this mount offers unparalleled guide precision and payload abilities.
- Zero-Backlash Harmonic Drive: Delivers ultra-smooth motion with microscopic repeatability — perfect for deep-sky imaging, planetary stacking, and long-duration tracking.
- Auto Homing: Integrated homing sensors ensure that your mount always knows its way home.
- Through-axis power hub & USB on dovetail: Týr delivers up to 7.5A of power and USB connectivity routed directly through the dovetail, ensuring clean, integrated cable management and minimal external wiring.
- Zero-Shift Polar alignment: You can still perform fine-adjustments of Altitude knob on the polar wedge, with the locking bolts tightened. You will no longer experience jumps in alignment when doing final adjustments during polar alignment.
- Compact, Rigid Design: CNC-machined from aerospace-grade 7075 aluminum for maximum stability and minimal vibration.
- Autoguider & ASCOM/INDI-Compatible: Seamlessly integrates with your existing astrophotography workflow. You can use PHD2, N.I.N.A., APT, KStars-Ekos or any other ASCOM or INDI software.
- Maintenance-Free: Run your sessions in total confidence, no drift.
- Wi-Fi OTA Firmware Update even without the use of a computer.
