About the Celestron Advanced VX 8" Newtonian Telescope... Large aperture Celestron Telescope at an affordable price, the Advanced VX 8" Newtonian provides 78% more light-gathering abilities compared to the 6" model. The parabolic primary mirror incorporated into the Celestron Advanced VX 8" Newtonian Telescope design minimizes spherical aberration to produce a sharper image near the edge of the field of view. This Celestron Telescope is great for intermediate visual observers and beginning astroimagers looking for a large aperture with lots of light-gathering power. As you grow in your hobby, you can continue to enjoy all the high-level features of the Advanced VX. 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 8" Newtonian 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 with your Celestron CCD Camera 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. Celestron Advanced VX 8" Newtonian Telescope Features... 8" (200mm) f/5 optical design gives excellent wide field views Parabolic primary mirror minimizes spherical aberration to produce a better image Integer gear ratios and permanently programmable Periodic Error Correction eliminates recurring track errors from the worm gear. 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. Improved electronics contain increased memory for future expansion NexStar+ hand control offers multiple language programming (English, French, Italian, German, Spanish) Celestron Advanced VX 8" Newtonian Telescope Specifications...
