I'm new to mechanical engineering, gears, and motors. Coming from a software/hardware background, I am trying to understand how to leverage gear reduction to maximize the torque output of a stepper motor for an equatorial mount. The speed can be very slow so I would like to focus on maximizing torque for a heavy payload.

By my understanding, the output torque is the product of the input torque and the gear ratio. Is this the same for the "holding torque" of a gear system? Is the output holding torque the product of the input holding torque and the gear ratio?

Yes, the holding torque goes up proportionally with the gear ratio. Plus the friction of the gear train, and any other seals, bearings along the gear train that add friction.
