MirroSky GX35 Smart EQ Mount with 53mm ED Guide Scope and Imaging Module
The MirroSky GX35 is designed for astrophotographers who need a lightweight, versatile mount that supports both equatorial and Alt-Az modes. Its belt drive system ensures smooth, accurate tracking, which is essential for long-exposure imaging. Unlike traditional mounts, it includes an integrated guide scope and imaging camera, streamlining setup for mobile astrophotography. The use of worm gear and synchronous belt drives minimizes backlash, yet the reliance on a mobile app for control may be less appealing to those preferring physical controls. Compared with larger mounts, the GX35’s portability is a significant advantage, but its lower payload capacity limits heavier equipment.
Pros:- Lightweight at only 8.8 pounds, easy to transport
- Supports both equatorial and Alt-Az modes for versatility
- Includes integrated guide scope and imaging camera for streamlined imaging
- Uses worm gear and synchronous belt for precise tracking
Cons:- Requires a mobile device and app for operation, which may be less intuitive
- Payload capacity appears inconsistent, limiting heavier setups
Best for: Beginners and mobile astrophotographers seeking a compact, all-in-one setup
Not ideal for: Users with heavy telescope gear or those preferring fixed observatory setups
- Mount Weight:8.8 lb (4 kg)
- Payload Capacity:22 lb (10 kg)
- Mount Modes:Equatorial and Alt-Az
- Drive System:Worm gear and synchronous belt
- Guide Scope:53mm ED
- Camera:Sony IMX662 CMOS
Our verdict“A smart, portable choice for astrophotographers who prioritize integrated imaging and ease of transport.”
Celestron CGX Computerized German Equatorial Mount and Tripod, 55 lb Payload
The Celestron CGX is tailored for serious amateur astronomers and astrophotographers who require a robust platform capable of supporting large telescopes. Its belt drive system offers smooth, precise movement with minimal backlash, which is vital for high-quality imaging.

Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
When selecting an equatorial mount with a belt drive system, consider your specific needs regarding portability, payload capacity, control interface, and imaging goals. Belt drives enhance tracking accuracy by reducing gear backlash and ensuring smooth motion, but they also come with tradeoffs in weight and complexity. Understanding these factors helps in choosing a mount that balances performance with practicality.
Portability and Size
If you frequently set up at different locations or have limited space, a lightweight, compact mount like the MirroSky GX35 is advantageous. Larger, heavier mounts like the Celestron CGX are better suited for permanent observatories or those with dedicated setups, where stability and payload support outweigh portability considerations.
Payload Capacity and Equipment
Matching the mount’s capacity with your telescope and imaging gear is critical. The GX35 supports up to approximately 10 kg, making it suitable for smaller telescopes and cameras. The CGX’s 55 lb capacity accommodates larger, heavier optical tubes and multiple accessories, but this also increases weight and setup effort.
Control and Software
Mobile app control, as seen with the GX35, offers quick setup and convenience but may lack the robustness of a dedicated hand controller. The CGX’s integrated NexStar+ controller provides extensive features, object databases, and remote operation capabilities, appealing to advanced users comfortable with more complex interfaces.
Precision and Tracking
Both systems employ belt drives, which significantly improve tracking accuracy compared to traditional gear systems. The choice depends on your imaging needs: for long exposures and high-precision astrophotography, the smoother, more reliable motion of both mounts is beneficial, with the CGX providing added stability for larger setups.
Frequently Asked Questions
Why choose a belt drive system in an equatorial mount?
Belt drive systems reduce gear backlash and vibrations, resulting in smoother, more precise tracking—crucial for astrophotography. They also tend to operate more quietly and with less wear over time compared to traditional worm gear systems, offering better long-term performance.
Is a lightweight mount like the GX35 suitable for serious astrophotography?
The GX35 is better suited for beginner or mobile astrophotographers due to its portability and integrated features. While it offers adequate tracking precision for many applications, it may not support very heavy or complex imaging setups that require the stability and capacity of larger mounts like the CGX.
What are the main tradeoffs between these two mounts?
The GX35’s portability and integrated imaging make it ideal for on-the-go use but limit its payload and durability for heavy setups. Conversely, the CGX’s high capacity and advanced control features support more ambitious projects but at the expense of weight, size, and complexity—making it less suitable for casual or portable use.
Can these mounts be used for remote or automated observing?
Yes, both mounts support remote operation, but through different methods. The GX35 relies on a mobile app, which is convenient for quick setups, whereas the CGX’s wired control system with a dedicated hand controller allows for more sophisticated automation and integration with software like planetarium programs or remote observatory setups.
What kind of equipment can I mount on these systems?
The GX35 supports lighter telescopes and accessories up to about 10 kg, making it ideal for small refractors or SCTs with cameras. The CGX can handle larger optical tubes up to 55 pounds, suitable for larger reflectors, refractors, and extensive imaging rigs—though this requires more space and setup time.
Conclusion
For beginners, hobbyists seeking portability and ease of use, the MirroSky GX35 offers an accessible, integrated option. Serious astrophotographers or those with larger equipment should lean toward the Celestron CGX for its higher capacity, advanced controls, and stability. If space and weight are constraints, the GX35 is the clear choice; for heavy, long-term setups with demanding imaging needs, the CGX delivers unmatched support.
