Description
For those looking to step up to an 11-inch optical tube, Advanced VX is a great option. Not only is it one of Celestron’s most affordable 11-inch telescopes, it is also one of the most portable. The Advanced VX mount is strong enough to support this optical tube assembly and a couple of small accessories, yet weighs far less than some of our other 11-inch telescope kits. As far as optics go, the 11-inch SCT gathers 41% more light than the 9.25-inch model. You also get our StarBright XLT coatings for even better light transmission.
About the Mount
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 and autoguider support. You’ll be able to track through long exposures using permanently programmable periodic error correction. Image across the meridian without doing a meridian flip, so you can seamlessly image the best part of night sky. Advanced VX features significantly larger base castings than our previous design, improving stability under heavier loads. Improved motors offer more torque and can handle slight load imbalances with ease.
