The Celestron 8 Edge HD Advanced VX Telescope combines the groundbreaking new Advanced VX mount with Celestron's best optics, the Edge HD optical system. This setup offers the astroimager maximum versatility because it allows up to 3 different f-stop configurations. Users can attach a camera to the rear of the telescope & shoot at f/10, or attach the 8-inch focal reducer (not available yet) & shoot at f/7. Also, the Edge HD is Fastar/ Hyperstar compatible, giving imagers the option to shoot at ultra-fast f/2. Whichever configuration you choose, the Edge HD technology gives you pinpoint stars all the way to the edge of the CCD sensor. The Advanced VX mount was designed to provide optimum imaging performance for smaller telescopes. This means the smaller telescope can now take advantage of All-Star Polar Alignment & autoguider support. You will be able to track through long exposures using permanently programmable periodic error correction & image across the meridian without doing a meridian flip. This means you can seamlessly image the best part of night sky. The Advanced VX features significantly larger base castings than the previous design, which improves stability under heavier loads. The enhanced motors offer more torque & can handle slight load imbalances with ease. This setup is simple enough for a beginner to use, but can also provide years of enjoyment for sophisticated astroimagers. Features
