The Powerguide II must be installed by Questar factory technicians in place of the existing AC drive motor in the drive base of the fork mount of your older 7" Questar telescope. It cannot be installed in the field. This requires that your fork mount and drive base be shipped back to Questar for the installation. Shipping both to and from the factory is the buyer’s responsibility.

The Powerguide II powers the Questar at a sidereal tracking rate for up to 50 hours from a single 9-volt transistor radio battery, freeing you forever from the need to stay near an AC outlet to observe. Pushbuttons on the Powerguide II hand control allow single axis guiding in right ascension for astrophotography (or dual axis by adding an optional declination motor). Pressing the east and west buttons simultaneously when the scope is turned on converts the drive to a lunar tracking rate. Pressing the north and south buttons simultaneously when the scope is turned on converts it to southern hemisphere operation, allowing you to use a Questar anywhere in the world without having to worry about finding the proper power frequency or voltage. With a Powerguide II, the Questar is truly a universal telescope.
