About this product

Model:  cel_700_makcass_vx
Part Number:  12035

The 700 Maksutov-Cassegrain Advanced VX telescope (Advanced VX 700 Mak) is a specialized instrument designed for detailed, high contrast views that sets a new standard in mid-level telescopes. With its Maksutov-Cassegrain optical tube and the sturdy Advanced VX equatorial mount and tripod, this kit provides unparalleled views of the planets and up-close views of the lunar surface, including craters and maria.

Astronomers located in urban areas will especially appreciate the Mak’s ability to bring out more contrast in celestial objects. But since the entire kit disassembles into separate, lightweight, and manageable pieces, it’s also a great choice for transporting to dark sky sites.

The new Advanced VX mount is specifically designed to provide optimum imaging performance for smaller telescopes. Features include permanent programmable periodic error correction, all star polar alignment, autoguider support and the ability to image across the meridian without doing a meridian flip so you can seamlessly image the best part of night sky. Compared to the earlier CG5-GT mount the Advanced VX also has larger base castings for improved stability under heavier loads and upgraded motors for more torque. 

Maksutov-Cassegrain Optical Design

The 700 Maksutov-Cassegrain is a catadioptric telescope, which means the optical design includes both a lens and a mirror. The light coming through a Mak passes through the corrector lens to the primary mirror and back to a spherical secondary mirror before it hits the eyepiece. Images are bright, sharp, and virtually free of chromatic aberration. 

Astronomers located in urban areas will especially appreciate the Mak’s ability to bring out more contrast in celestial objects. But since the entire kit disassembles into separate, lightweight, and manageable pieces, it’s also a great choice for transporting to dark sky sites.

The optical design offers several unique benefits. Instead of a secondary mirror, the Mak features a “secondary spot” of reflective coating applied directly to the inside of the corrector plate. Because of this, the telescope does not require frequent collimation like a Schmidt-Cassegrain. Also, the secondary spot is significantly smaller than a traditional Schmidt-Cassegrain secondary mirror, giving the Mak its signature high-contrast views.

One important thing to note about Maksutov-Cassegrain telescopes is that the larger, heavier Maksutov corrector plate takes longer to cool down and adjust to ambient air temperature compared to a Schmidt-Cassegrain of the same aperture.

Advanced VX & Tripod

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, SkyAlign, 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.

Computerized German Equatorial Mount

The Advanced VX is the smallest of Celestron’s German equatorial mounts. The computerized GoTo capability automatically tracks objects as they move across the night sky. The Advanced VX mount includes ports for a hand control, an autoguider, and 2 AUX ports for optional accessories.  The NexStar+ hand control gives you instant access to all the functions your mount has to offer. With automatic slewing and menu descriptions, astronomers of all skill levels can master this mount in just a few observing sessions. The Advanced VX also has an impressive tripod for its class with 2”-diameter steel tripod legs, providing an extra-wide stance for improved stability.

Payload capacity
The payload capacity for the Advanced VX is 13.5kg (30 lb). It offers a sturdy platform for the 7” Maksutov-Cassegrain optical tube, even when paired with optional accessories like StarSense AutoAlign, Focus Motor, a finderscope, and a camera. Celestron's payload capacity does not include the weight of the counterweights.
