The Advanced VX (AVX) sets a 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” Newtonian telescope is an excellent entry- to mid-level setup that can grow with you. The Newtonian optical design is excellent for visual observing and offers you the largest aperture for the price. The parabolic primary mirror minimizes spherical aberration to produce a sharper image near the edge of the field of view. The 8” Newtonian optical tube offers 78% more light gathering ability than the 6” Newtonian optical tube.
The Advanced VX mount is designed to provide superior performance for smaller telescopes while taking advantage of Celestron’s most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, and permanently programmable periodic error correction (PPEC).
If you’re an experienced imager, you’ll love taking this portable mount to a dark sky site and enjoying all the conveniences of a larger observatory mount. Or, if you’re new to imaging, Advanced VX will help you get started with the hobby and keep up with your needs for years to come.
