The 700 Maksutov-Cassegrain Advanced VX (AVX) 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.
Maksutov-Cassegrain Optical Design
The Mak 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.
The Maksutov-Cassegrain’s 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.
The payload capacity for the Advanced VX is 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, and a camera. Celestron's payload capacity does not include the weight of the counterweights.
Dual saddle plate
As of early 2019, Advanced VX mounts now include a new dual saddle plate that accommodates both CG-5 and CGE-style dovetails. Switching between the two saddle plates is as simple as moving the hand knobs into a separate set of holes. Now you can use your Advanced VX mount not only with the 7” Mak, but virtually any optical tube within Advanced VX’s weight limit. Compatible with Vixen format dovetails 100mm or longer, not compatible with Losmandy D format plates (regardless of plate manufacturer).
