Starizona Balance Box - Current Meter for Accurate Mount Balance and Troubleshooting

The Starizona Balance Box is used to measure the current being drawn by a telescope mount to determine if the mount is properly balanced. With some mounts, the usual method of balancing by loosening the clutches and pushing the scope up and down is made difficult by mount axes that stick with heavy grease and do not move freely when the clutches are loose.

The idea behind the Balance Box is that the amperage drawn by the mount should be the same in both directions for a given axis when the mount is properly balanced.  When moving the mount in opposite directions in one axis, for example east then west, the measured amps will be different when the mounts is out of balance.  By adjusting the weight until the amps are the same in both directions, the mount will be properly balanced.

To use the Balance Box, simply plug it inline between your power supply and mount. The box uses a standard 2.1mm plug which will work with Celestron, Skywatcher, Astro-Physics and other popular mounts.


The Balance Box also can be used to troubleshoot issues with mount electronics and motors by monitoring the voltage and current being drawn as the mount moves.  It can also monitor the voltage from your power supply.
