EQ5 dual axis controller gearing

[luka]

Hi

Does anyone know what the gearing is for the dual axis motors that come with the EQ4/EQ5 dual axis drive that looks like this (not GOTO).

I think EQ5 has a reduction of 144x but I am not sure of the gearing of the motors.

I am trying to adapt the OnStep GOTO system to my EQ5.

Thanks
Luka
