Trident GTR - Direct Friction Drive Telescope Mount

The Trident GTR is the next generation of Trident P75, further developing an already great platform. There is no other mount that comes close to the payload or precision of a Trident for the same price. 

The JTW Trident GTR further builds on the success of the P75 with additional features. The mount now includes a PEC sensor, failsafe homing, GPS, magnetic failsafe brake & optional environmental sensors.  The mount also now features internal cabling and is 25% lighter than a P75 at 30 kg mount head weight.

Addition of a PEC sensor to Direct Friction Drive is a particularly potent addition as our drive system has almost textbook periodic error, a near perfect sine-wave with 16 minute period. 

Our unique direct friction drive system combined with a mount that is designed to be easy to manufacture and maintain yields an unbeatable price/performance ratio. This mount is optimised for remote use and excels at multi-instrument payloads. 

The Trident GTR is essentially maintenance free, any part that might need replacing can be replaced in a matter of minutes, making this system ideal for remote hosting services or people who require a reliable mount with low cost of ownership.
