The Advanced VX sets a new standard in mid-level telescopes, providing many of the features found on Celestron's most sophisticated German equatorial mounts at an extremely affordable price. The Advanced VX 8" EdgeHD telescope combines the groundbreaking new Advanced VX mount with Celestron's best optics, the EdgeHD optical system. This setup offers the astroimager maximum versatility allowing up to 3 different f-stop configurations. Users can attach a camera to the rear of the telescope and shoot at f/10 or attach our 8" EdgeHD focal reducer to shoot at f/7. Additionally, EdgeHD is Fastar/Hyperstar compatible, giving imagers the option to shoot at ultra-fast f/2. No matter which configuration you choose, EdgeHD technology gives you pinpoint stars all the way to the edge of the CCD sensor. The Advanced VX mount is designed to provide superior performance while taking advantage of Celestron's most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, SkyAlign, and permanently programmable periodic error correction (PPEC).
