MirroSky by Spectrum Optical GX35 Smart EQ Mount with Guide-Scope
The MirroSky GX35 prioritizes portability without sacrificing tracking accuracy, thanks to its belt drive and worm gear system. Weighing only 8.8 pounds, this mount is designed for astrophotographers on the go, with a built-in guidescope and a compatible app that simplifies remote control and monitoring. Its 28.5-pound payload limit makes it suitable for smaller telescopes and imaging gear, making it ideal for traveling astronomers or those with limited space. While setup can be complex for newcomers, the integrated guidescope and app integration streamline the process for more experienced users. The GX35’s lighter weight means it’s less suited for large, heavy equipment but excels in ease of transport and deep-sky imaging for intermediate users.
Pros:- Lightweight and easy to transport
- Integrated guidescope and camera for deep-sky imaging
- App-controlled operation for remote monitoring
Cons:- Limited payload capacity for larger gear
- Setup can be challenging for beginners
Best for: Travelers and deep-sky astrophotographers with moderate gear

Our verdict“A compact, feature-rich mount that excels in portability and guided astrophotography for intermediate users.”
How We Picked
Our selection process focused on mounts featuring belt drive systems known for precision and smooth tracking. We prioritized models that balance payload capacity, portability, and ease of use, aiming to highlight options suitable for both serious astrophotographers and enthusiasts. Technical specifications such as drive quality, motor type, and control features were key factors. We also considered user feedback regarding setup complexity, reliability, and overall value, ensuring each pick offers a distinct role in the market.
Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
When selecting an equatorial mount with a belt drive system, consider your primary use—whether astrophotography, visual observation, or portability. The key factors include payload capacity, motor precision, portability, and control features. Belt drive systems are favored for their smooth, quiet operation and reduced gear backlash, which improve tracking accuracy. However, these benefits come with tradeoffs in size, complexity, and cost. Understanding your specific needs will help determine whether you should lean toward a heavier, feature-rich mount or a lighter, more portable option.
Payload Capacity and Stability
If you plan to use large telescopes or heavy imaging gear, prioritize mounts with higher payload capacities like the Celestron CGX. For lighter setups or travel-focused imaging, smaller mounts like the MirroSky GX35 are more manageable. Remember, a mount’s stability is just as important as its weight capacity, especially for long exposure astrophotography.
Portability and Ease of Setup
For astrophotographers who travel frequently or set up in different locations, a lightweight, quick-setup mount like the GX35 offers significant advantages. Conversely, if your setup remains stationary in an observatory, weight and bulk are less of a concern, and a more robust mount like the CGX provides better stability.
Control and Automation Features
Advanced computerized controls, such as the NexStar+ system in the Celestron CGX, facilitate precise target acquisition and tracking, especially for astrophotography. The MirroSky’s app control simplifies operation for users comfortable with digital interfaces but may require familiarity with setup procedures. Choose based on your comfort with technology and need for automation.
Budget Considerations
Higher-end mounts like the CGX come with a higher price tag, justified by their capacity and features. Budget-conscious users or those just starting out might prefer the MirroSky GX35, which offers excellent portability and features at a lower cost, though with some limitations in payload and complexity.
Frequently Asked Questions
What are the main advantages of a belt drive system on an equatorial mount?
Belt drive systems reduce gear backlash and provide smoother, quieter operation compared to traditional worm gear setups. This results in more precise tracking, which is essential for astrophotography, especially during long exposures. Belt drives also tend to wear less over time, offering better durability and consistency for demanding applications.
Is a heavier mount always better for astrophotography?
Not necessarily. While a heavier mount like the Celestron CGX offers higher stability and payload capacity, it can be cumbersome to transport and set up. For many users, especially those who travel or have limited space, a lighter mount like the MirroSky GX35 can provide excellent tracking and imaging quality without the bulk, though it supports less weight and may require more careful handling.
Can I use these mounts for visual observing as well as astrophotography?
Absolutely. Both mounts are suitable for visual observing, but their features optimize different uses. The CGX is better suited for astrophotography due to its stability and advanced control, while the GX35’s portability makes it convenient for quick visual setups or light astrophotography sessions. Your choice depends on whether you prioritize mobility or maximum stability.
Are belt drive systems more reliable than gear drives?
Belt drives can be more reliable in terms of delivering smoother and more precise tracking, especially when properly maintained. They typically exert less stress on components and wear down more slowly. However, they require proper tensioning and alignment, and in some cases, may be more complex to repair or replace if issues arise.
What should I consider if I want to upgrade my mount in the future?
If future upgradeability is a concern, look for mounts with modular components and good support for accessories like guiding scopes and cameras. Consider mounts with higher payload ratings and more advanced control systems, so your investment remains versatile as your equipment and skills grow. Compatibility with software and accessories is also important for seamless upgrades.
Conclusion
If you primarily focus on astrophotography with heavy equipment and want a permanent setup, the Celestron CGX offers unmatched payload capacity and automation despite its weight and complexity. For those who value portability, ease of transport, and moderate astrophotography, the MirroSky GX35 provides a capable, lightweight alternative. Beginners and casual users should lean toward the GX35, while experienced astrophotographers with heavier gear will find the CGX more suitable for their needs.
