Our verdict“A versatile, portable mount ideal for deep space imaging enthusiasts who value integrated guidescopes and app control.”
Celestron CGX Computerized German Equatorial Mount & Tripod, 55 lb Payload
The Celestron CGX exemplifies strength and control, supporting up to 55 pounds of equipment. Its belt drive system ensures smooth, quiet operation, which is critical during long astrophotography sessions. The computerized hand controller includes a database of 40,000 objects, guiding tours, and remote operation capabilities. Compared to the MirroSky GX35, the CGX is heavier—over 100 pounds—and more complex to set up, but it excels in stability and automation for serious astronomers supporting large telescopes. Its internal cabling and robust tripod make it a reliable choice for fixed observatories or dedicated setups.
This mount makes the most sense for experienced users needing to support large payloads and automate their imaging sessions. It’s less suitable for portable use or beginners who might find its weight and complexity overwhelming.
Pros:- Supports heavy payloads up to 55 lbs, ideal for large telescopes
- Advanced computerized control with extensive object database
- Remote operation and guided tours enhance usability
- Sturdy stainless steel tripod ensures stability
Cons:- Very heavy, making transport and setup challenging
- Complex assembly requiring technical skill
- Higher price point, less accessible for casual users

Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
Choosing the right equatorial mount with belt drive involves balancing portability, payload capacity, automation, and your specific astrophotography needs. Belt drives excel at providing quieter, smoother tracking, which is vital for astrophotography accuracy. When evaluating these mounts, consider how much gear you plan to support, whether you need remote operation, and how much space and effort you can dedicate to setup. This guide highlights key factors to help you decide which features matter most.
Understanding Belt Drive Benefits
Belt drive systems reduce gear backlash and noise, offering smoother, more precise tracking compared to traditional gear systems. This improvement is especially noticeable during long exposures, minimizing star trailing and enhancing image sharpness. However, belt drives can be more complex and slightly more expensive, often requiring careful maintenance and setup. Your choice should depend on how critical tracking quality is for your astrophotography goals.
Portability vs. Power
If you frequently move your setup, a lighter, more compact mount like the MirroSky GX35 makes sense, despite its lower payload capacity. Conversely, if you plan to support large telescopes and do astrophotography from a fixed location, a heavier, more robust mount like the Celestron CGX offers stability and power at the expense of portability. Consider your typical observing environment when making this decision.
Automation and Control Features
Modern mounts often include app control, database-driven go-to systems, and remote operation. The MirroSky GX35’s app compatibility suits users who want quick setup and remote imaging in a portable form. The Celestron CGX’s advanced software and internal cabling support complex, automated sessions, ideal for users who prioritize precision and convenience over weight. Your familiarity with control software can influence which mount fits best.
Frequently Asked Questions
What are the main advantages of belt drive systems in equatorial mounts?
Belt drive systems significantly improve tracking accuracy by reducing gear backlash and noise. They deliver smoother, quieter operation, which is especially valuable during long-exposure astrophotography sessions. These benefits translate into sharper images and less need for post-processing corrections, making belt drives a worthwhile upgrade for serious astronomers.
Is a belt drive system more maintenance-intensive than traditional gear drives?
Compared to traditional gear drives, belt systems typically require less lubrication and adjustment, but they can be more sensitive to belt tension and alignment. Proper maintenance involves periodically checking the belt tension and inspecting for wear, especially if you use the mount frequently or in challenging conditions. When well-maintained, belt drives tend to be reliable and long-lasting.
How important is payload capacity when choosing an equatorial mount?
Payload capacity determines how much weight your mount can support safely, directly affecting the size and type of telescopes and accessories you can use. Exceeding this limit risks poor tracking, vibrations, or even damage. Carefully match your planned gear load with the mount’s rated capacity to ensure stable, accurate tracking, particularly for astrophotography.
Can I upgrade a conventional gear drive mount to a belt drive system?
In most cases, upgrading involves replacing or modifying the gear components, which can be complex and sometimes impractical depending on the mount’s design. Some mounts are designed with belt drive compatibility in mind, making upgrades easier. Consulting with the manufacturer or a professional technician can help determine if an upgrade is feasible and worthwhile.
What should I consider if I want a mount for both astrophotography and visual observing?
For dual-purpose use, look for a mount with high tracking precision, stability, and smooth motion, essential for astrophotography, while also being easy enough to set up for visual observing. Belt drives contribute to smooth tracking, but make sure the mount supports your preferred payload, offers reliable go-to functions, and is manageable in size and weight for your typical observing environment.
Conclusion
If you value portability and ease of use, the MirroSky GX35 is a compelling choice, especially for deep space imagers on the move. For those who require support for large telescopes, advanced automation, and don’t mind the added weight, the Celestron CGX stands out. Beginners should lean toward simpler, lighter setups, while seasoned astrophotographers demanding precision and heavy gear will find the CGX more aligned with their needs.
