Our verdict“The Celestron CGX stands out for its combination of high payload capacity and sophisticated features, making it ideal for serious astrophotographers who prioritize performance over portability.”
Celestron Advanced VX Computerized German Equatorial Mount – 30lb Payload
The Celestron Advanced VX offers a solid balance between performance and portability, supporting up to 30 pounds. Its belt drive system ensures quieter operation and smoother tracking than older gear-based mounts, though it isn’t quite as refined as the CGX’s. The mount features a sturdy stainless steel tripod with 2-inch diameter legs, providing excellent stability for most amateur astrophotography. Its computerized hand control includes a database of over 40,000 objects, along with multiple tracking modes like sidereal, solar, and lunar tracking. While it’s easier to transport and set up than the CGX, the payload limit means it’s best suited for mid-sized telescopes and lighter imaging gear. The main tradeoff here is that it doesn’t support as heavy a payload, but its lighter weight and simpler setup make it appealing for many users.
Pros:- Supports up to 30 lb payload, suitable for most mid-sized telescopes
- Sturdy stainless steel tripod with 2-inch legs ensures stability
- Advanced computerized controls with a large object database
- Multiple tracking modes improve observation flexibility
Cons:- Relatively heavy to carry (total kit weight around 47 lbs)
- Setup may be complex for first-time users
- Limited to 30 lb payload, less suitable for large telescopes
Best for: Amateurs seeking a reliable, portable mount with advanced features for small to medium telescopes
Not ideal for: Heavy-duty astrophotography setups or users requiring maximum payload capacity
- Weight Capacity:30 lbs

How We Picked
Our selection process focused on mounts that incorporate belt drive systems, prioritizing stability, precision, and ease of use for astrophotography. We examined technical specifications, payload capacity, build quality, and user features like computerized controls and software compatibility. We also balanced these technical merits against practical concerns such as weight, setup complexity, and price. The goal was to identify options that offer reliable belt drive performance while catering to different user needs—whether for heavy-duty imaging or more portable use.
Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
Choosing an equatorial mount with belt drive systems involves balancing payload capacity, portability, and feature complexity. Belt drives improve tracking accuracy and reduce noise, which is especially beneficial for astrophotography. Your decision should hinge on your telescope size, imaging needs, and whether you prioritize ease of transport or maximum stability. Understanding these factors helps narrow down the options to mounts that will deliver precise, quiet tracking without overwhelming your setup process.Payload Capacity and Telescope Size
Consider how heavy your primary telescope and accessories are, as this determines whether a mount like the CGX or the Advanced VX is suitable. Overloading a mount can compromise tracking accuracy and stability. For large, heavy telescopes, the CGX’s 55-pound capacity offers more peace of mind. Conversely, lighter setups can benefit from the portability and ease of setup of the Advanced VX, which supports up to 30 pounds.
Portability and Setup
If you frequently move your equipment, the weight and size of the mount become critical. The CGX’s weight (over 100 pounds) makes it less convenient for travel, while the Advanced VX, at about 47 pounds, strikes a better balance for portable use. Both require some technical skill to set up, but the simpler design of the VX can be more approachable for newcomers.
Tracking and Noise
Belt drive systems significantly cut down on gear backlash and operational noise, which improves image quality and user comfort. Both mounts incorporate this technology, but the CGX’s higher-end motors deliver even smoother tracking, especially important for long exposures. The tradeoff is higher cost and complexity, which may be unnecessary for casual observing.
Features and Software
Both mounts include computerized hand controls with extensive object databases, making targeting celestial objects straightforward. Additional features like guided tours or remote operation are more advanced in the CGX, ideal for dedicated astrophotographers. Simpler controls in the VX cater well to beginners or casual users who want reliable tracking without extra bells and whistles.
Frequently Asked Questions
What is a belt drive system on an equatorial mount?
A belt drive system replaces traditional gear trains with belts, which provide smoother, quieter operation and reduce gear backlash. This results in more precise tracking, especially important for astrophotography where even tiny deviations can blur images. Belt drives are generally more durable and require less maintenance, making them a popular upgrade in modern mounts.
Is a higher payload capacity always better?
Not necessarily. While a higher payload capacity allows for larger telescopes and accessories, it also adds weight and complexity. If your equipment is lighter, choosing a mount with a more modest capacity can lead to easier setup and better portability. Overloading a mount beyond its rated capacity can cause tracking issues and reduce the lifespan of the system.
How important is portability in choosing an equatorial mount?
Portability depends on how often you plan to move your setup. If you frequently attend observing sessions at different locations, a lighter, more manageable mount makes setup simpler. Conversely, if your setup remains fixed in one location, weight and transport become less critical, and you might prioritize stability and payload capacity instead.
Can I use these mounts for astrophotography?
Yes, both mounts are equipped with belt drive systems and computerized controls designed to support astrophotography. The CGX, with its higher payload and advanced features, is better suited for long-exposure imaging with larger telescopes. The Advanced VX is still capable but better suited for smaller setups or those just starting in astrophotography.
Are belt drive systems noisy?
Compared to traditional gear drives, belt systems operate more quietly because belts absorb vibrations and reduce gear backlash. This quieter operation is especially valuable during long imaging sessions, where noise can be distracting and potentially disturb sensitive equipment. Both mounts in this roundup feature belt drive technology, offering a noticeable reduction in operational noise.
Conclusion
For users who need maximum payload and are prepared for a heavier, more complex mount, the Celestron CGX makes a compelling choice. It’s ideal for dedicated astrophotographers with large telescopes seeking precise, quiet tracking and advanced features. The Celestron Advanced VX suits those looking for a more portable, affordable option that still delivers reliable tracking and good software support. Beginners or casual astronomers will appreciate its simplicity, while more experienced users can benefit from the added stability of the CGX if their budget and transport considerations allow.
