Engineered from the ground up
With astroimaging in mind, the new Advanced VX series from Celestron sets a new standard in mid-level telescopes. Advanced VX provides you with many of the features found on Celestron’s most sophisticated German equatorial mounts, at an extremely affordable price.

The new Advanced VX mount 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. You’ll 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. Advanced VX 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.

Experienced imagers will love taking this portable mount to a dark sky site, with all the performance of their larger observatory mount. Or, if you’re new to imaging, this mount will help you get started with the hobby and keep up with your needs for years to come.

Konusmotor-130 5" f/7.7 Reflector Telescope with RA Motor

The Konusmotor-130 5" f/7.7 Telescope with RA Motor from Konus is an ideal intermediate scope for making observations of the Moon and planets as well as brighter deep sky objects. The 5" primary mirror and anti-reflection multicoated optics ensure images are bright and clear. This German equatorial mount is a step-up from a beginner version with the addition of a Right Ascension tracking motor that counteracts the Earth's rotation and keeps your subjects centered for longer observation sessions. Using the motor to track, instead of the more common manual cable not only ensures steady and smooth movement, but it also greatly reduces vibrations. The manual slow-motion declination cable allows for adjustments if necessary. To further reduce vibrations Konus outfits the focuser with a motor that can achieve a smooth fine focus that manual focusing often cannot.

Assembled as a complete observation platform, the scope includes an adjustable-height aluminum tripod, a red dot finderscope for faster alignment and sighting, and two eyepieces. The 10mm eyepiece produces 100x power, and the 17mm produces 59x. A filter is also included for users to safely make detailed observations of the Moon. To transport and carry the OTA and tripod are two bags with zipper closures.
