Engineered from the ground up with astroimaging in mind, the new Advanced VX series from Celestron sets a new standard in mid-level telescopes. Advanced VX provides you with many of the features found on Celestron's most sophisticated German equatorial mounts, at an extremely affordable price. The new Advanced VX mount was specifically designed to provide optimum imaging performance for smaller telescopes. Now your smaller telescope can take advantage of All-Star Polar Alignment & autoguider support. You'll be able to track through long exposures using permanently programmable periodic error correction. Advanced VX features significantly larger base castings than our previous design, improving stability under heavier loads. enhanced motors offer more torque & can handle slight load imbalances with ease.
