GTD MoFoD MKII Fork Friction Drive Mount
The GTD MoFoD MKII Fork Friction Drive Mount, from Gemini Telescope Design, is the ideal solution for demanding applications (public, school, society or professional observatories). Our Modular Fork Design allows changing the OTA by sliding the fork arms in or out. MOFOD Fork Mount is the most stable observatory class mount with remote control.

Why a Fork? Why not!
Gemini MoFoD MKII Fork Mounts have the following advantages over German Equatorial mounts
- No counterweight needed – smaller inertia can be rotated faster.
- No meridian flips needed – no lost time.
- No guider recalibration or field rotation needed.
- No collision with the pier is possible – more safety in remote mode.
Forks were not as flexible to changing OTA as German Equatorial mounts. Our Modular Fork Design allows changing the OTA by simply sliding the fork arms out or in. Any compact telescope from 340-mm to 680-mm wide can ride this fork.
What is Modular Fork Design (MoFoD)?
Our MOFOD Fork Mounts are easily separated in 4 main parts: the RA base, the horizontal arm (tube) and the two fork arms. The orthogonality of the main axes is adjustable, ensuring maximum pointing precision.
Two persons can do the setup in 1 hour with a set of allen keys. Watch the time lapse here!
MoFoD is served by our proprietary ultra precise friction drive system with important advantages: silent and efficient operation means small ecological footprint, zero backlash means easy guiding combined with precise tracking, effective brake even without power means safety at all times. Longevity is guaranteed by high tech materials, reflecting in the 5 year warranty period.
To ensure precision in pointing and reliability in remote mode, high resolution encoders are fitted on both axes. The encoders have an absolute reference that enables the driver to find the home position after a blackout. The stepper motors have 0,1″ resolution.
The optional sliding weight inside the horizontal fork arm allows fine balancing the OTA for best operation. Coarse balancing is achieved by sliding both fork arms with the OTA in the correct direction.
