Celestron Advanced VX 8in Newtonian Telescope

Celestron Advanced VX 8in Newtonian Telescope. The parabolic primary mirror on this Telescope from Celestron minimizes spherical aberration to produce a sharper image near the edge of the field of view. The Celestron VX Newtonian Advanced 8in 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 Celestron Advanced VX Newtonian Scope. The mount on the Celestron Newtonian Advanced VX Telescope 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. With this Celestron Newtonian Telescope 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. The Celestron 8in Advanced VX Newtonian Telescope 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.
