About the Celestron Advanced VX 6" Refractor Telescope... For planetary imaging and brighter deep-sky objects, many astroimagers say there'''s no better choice than a Celestron Refractor Telescope. Unlike Schmidt-Cassegrain or Newtonian telescopes that have a secondary mirror, refractors offer no obstruction of the aperture, giving you the highest possible contrast. The Celestron Advanced VX 6" Refractor Telescope features an f/8 objective lens, which can be paired with one of Celestron'''s Nightscape CCD Cameras to image brighter deep-sky objects or the Celestron NexImage 5 Solar System Imager to create dazzling images of the planets. About the Celestron Advanced VX Mount... The new Advanced VX mount was specifically designed to provide optimum imaging performance for smaller Celestron Telescopes. Now your Celestron Advanced VX 6" Refractor 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. Use a Celestron CCD Camera to 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 the previous design, improving stability under heavier loads. Improved motors offer more torque and can handle slight load imbalances with ease. Don'''t forget... Additional Celestron Telescope Eyepieces are also available - along with an extensive array of Celestron Telescope Accessories, too! Celestron Advanced VX 6" Refractor Telescope Features... 6" (150mm) f/8 objective lens is perfect for high contrast planetary views 2" Focuser allows use with 2" and 1.25" accessories Integer gear ratios and permanently programmable Periodic Error Correction eliminates recurring track errors from the worm gear. Autoguider port for long exposure imaging New motors offer improved tracking performance & provide more power to overcome load imbalances Updated industrial design offers more rigidity, less flexure and improved aesthetics New design allows viewing or imaging across the meridian without interference from the motors housings Improved latitude range. Can be used between 7 - 77 degrees latitude.
