The GT1 is a controller for stepper motors with goto compatible functionality on all types of mounts, being able to set the number of steps per revolution of a nut and a revolution. It is also compatible with any type of motor, as it can supply up to 1A of current for each winding.
You can wire the connected steppers in any order and set a parameter from the configuration application to find the right combination, without having to re-solder the connection wires.
It is equipped with these inputs / outputs:
- Synscan Hand-set compatible input.
- Autoguider input
- Stepper output
- Right Ascension Stepper output
- Declination Stepper output
- 12v Power input
Being compatible with the Merlin protocol it can be connected directly to the computer and driven by software like EQMOD.
The precision in low speed, including autoguide and sidereal tracking, is 64 microsteps.
The maximum speed has no limit, but must be appropriate to the load and weight of the telescope and the power of the engines.
The configuration software – downloadable here – can set motor parameters, go-to acceleration and maximum speed.
The firmware is upgradable.
