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 9.25" Schmidt Cassegrain telescope is ideal for imagers and visual observers. The 9.25" optical tube offers 33% more light gathering ability than an 8" telescope. The Schmidt-Cassegrain design also eliminates chromatic aberration, making it a good choice for entry-level astroimaging. Each individual piece of this telescope (optical tube, tripod, etc.) does not exceed more than 20 lb making it easy for one person to transport and assemble.
The Advanced VX mount is designed to provide superior performance 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, any level of astronomer can master this mount in just a few observing sessions. The Advanced VX also has an impressive tripod for its class with a 2" diameter steel tripod legs providing an extra-wide stance for improved stability.
Payload capacity
The payload capacity for the Advanced VX is 30 lb. It offers a sturdy platform for any of the Advanced VX optical tubes, 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.
Dual saddle plate
As of early 2019, Advanced VX mounts include a dual saddle plate that accommodates both CG-5 and CGE-style dovetail. Switching between the two saddle plates is as simple as moving the hand knobs into a separate set of holes. You can use an Advanced VX mount with virtually any optical tube within its weight limit. Compatible with Vixen format dovetails 100mm or longer, not compatible with Losmandy D format plates (regardless of plate manufacturer).
Software
Celestron PWI Telescope Control Software
Your Ultimate Astronomy Software Suite
All current Celestron computerized telescopes include Celestron PWI (CPWI), the most advanced astronomy software suite provided with any consumer-grade telescope. Celestron's experts co-developed CPWI with the engineers at PlaneWave Instruments. The result is an all-in-one solution offering you many of the same features used on PlaneWave's observatory-class telescopes.
- Graphical planetarium interface with PointXP advanced mount modelling allows you to add 100+ points to your alignment model for the most accurate pointing and tracking possible
- Ideal for remote observatory setups: save and re-load your alignment and park your scope
- Provides a complete ASCOM telescope interface to allow control of the telescope from third party software applications

Starry Night Software
Included with your purchase is a free download of Celestron's Starry Night Special Edition Software. This advanced software by Simulation Curriculum offers detailed information about celestial objects and helps you plan your next observing or imaging session. The Special Edition software also allows you to control your telescope via computer.
I have an optical tube equipped with a Losmandy D dovetail mounting plate. Will this work with the improved Advanced VX (AVX) mount?
No, the Losmandy D dovetail plate will not fit the improved AVX mount. The improvement to the AVX mount allows it to be used with CGE format dovetail plates, but not Losmandy D format plates. The CGE and Losmandy D formats are similar, but not exactly the same. Losmandy plates are a millimeter or so wider, but CGE plates allow more surface area contact with the dovetail clamp. 
What prevents the Losmandy D plates from working with the improved AVX?
The improved AVX can accept a dovetail with a maximum width of 74.5mm. The Losmandy D plate is a bit wider than that. Also, the improved AVX requires the height of the dovetail undercut to be at least 10.2mm, and the Losmandy D has a dovetail undercut which shorter than that. 
So, how do I mount my optical tube with a Losmandy D dovetail plate onto the improved AVX?
You'll need to replace the Losmandy D dovetail plate with a compatible dovetail plate, such as the Celestron #94214 CGE Universal Mounting Plate.
I have a Losmandy D format dovetail plate, but it is not manufactured by Losmandy. Will it work with the improved AVX?
No, if the dovetail plate uses the Losmandy D format, then it is not compatible with the improved AVX, regardless of the manufacturer of the plate.
I have an optical tube equipped with a Vixen dovetail mounting plate. Will this work with the improved AVX mount?
Yes, the improved AVX, like the original AVX, is compatible with Vixen format dovetail plates. However, the plate must have a dovetail length of 100mm or greater.
Why does my Vixen dovetail, or CG-5 dovetail, need to have a dovetail length of at least 100mm?
The knobs on the AVX that hold the dovetail plate in place are spaced 90mm apart. If the dovetail length is less than 100mm, then both knobs cannot come into contact the dovetail simultaneously. See the below engineering drawing. 
My optical tube has a Vixen or CG-5 dovetail plate with a dovetail length of less than 100mm. How do I mount it onto the AVX?
You'll need to replace the dovetail plate with a compatible dovetail plate, such as the Celestron #94213 Universal Mounting Plate, CG-5.
What is the heaviest recommend load for mounting a camera in the Fastar / HyperStar configuration?
We recommend a load of no more than 25 lbs. at 4.2 inches away from the 9.25" Schmidt corrector.
