Design
Celestron's Advanced VX Mount is an integrated telescope support, alignment and guiding system and was specifically designed to provide optimum imaging performance for smaller telescopes. The mount holds a maximum instrument capacity of 30 lbs. This mount packs some of the features found on more sophisticated German Equatorial mounts, minus the added bulk or cost. Now your smaller telescope can take advantage of All-Star Polar Alignment and autoguider support. Advanced VX features significantly larger base castings than the previous design, improving stability under heavier loads.
Motors
To enhance tracking performance, the mount features permanently programmable Periodic Error Correction (PEC). PEC eliminates recurring track errors from the worm gear to prevent trailing and improve photographs. You’ll also be able to track through long exposures using the PEC. The Advanced VX improved motors offer more torque and can handle slight load imbalances with ease.

For enhanced pointing and tracking accuracy, the mount features Celestron's All-Star Polar Alignment. This system uses multiple guide stars to assist tracking across the night sky while keeping the optical tube parallel to the Earth's axis of rotation.
