More Details on Our Top Picks
MirroSky by Spectrum Optical GX35 Smart EQ Mount with Guide-Scope
The MirroSky GX35 stands out for its lightweight design, making it one of the most portable belt drive equatorial mounts. It integrates a 53mm guidescope and a dedicated imaging camera, enabling deep space astrophotography without the need for extensive additional equipment. Its worm gear and synchronous belt drives deliver precise tracking, essential for long exposures. However, this light frame also limits its payload capacity, making it less suitable for larger telescopes or heavy accessories. Compatibility with the MirroSky app simplifies control via mobile devices, a big plus for quick setup and adjustments. Compared with heavier mounts, this model sacrifices some capacity for mobility, making it ideal for dedicated astrophotographers who travel frequently and focus on imaging smaller targets.
Pros:- Lightweight and portable for easy transportation
- Integrated guidescope and imaging camera for deep space photography
- Supports precise tracking with worm gear and belt drives
- Compatible with MirroSky app for remote control
Cons:- Limited payload capacity for heavy equipment
- Complex setup process for beginners
- Additional accessories may be needed for full functionality
Best for: Advanced amateur astronomers who prioritize portability and integrated astrophotography features.
Not ideal for: Users planning to mount large telescopes or requiring maximum payload capacity.
- Weight:8.8 lb (4 kg)
- Payload Capacity:28.5 lb (12.9 kg)
- Counterweight:4 lb (1.8 kg)
- Main Gear Teeth:144 teeth
- Power Input:12V 3A
- Guidescope Diameter:53 mm
Our verdict“This mount is ideal for astrophotographers needing portability and integrated imaging capabilities but less suited for heavy-duty setups.”
Celestron CGX Computerized German Equatorial Mount & Tripod, 55 lb Payload
The Celestron CGX offers a robust solution for astrophotographers demanding high payload capacity and advanced computerized controls. Its belt-drive system ensures smooth, precise movements, essential when tracking large or heavy telescopes over long exposures. The mount’s 55-pound payload capacity makes it suitable for sizable setups, while the NexStar+ hand controller provides access to an extensive database of over 40,000 celestial objects and guided tours. While its power and control features are impressive, this model is notably heavier and bulkier, which may pose challenges for frequent transport or quick setups. Compared to the MirroSky GX35, the CGX is less portable but delivers more power and control for serious astrophotography projects.
Pros:- High payload capacity suitable for large telescopes
- Advanced computerized controls with extensive object database
- Smooth belt-drive system for precise tracking
Cons:- Heavy and less portable for mobile setups
- Complex setup process for beginners
- Requires more space for storage and transport
Best for: Astrophotographers needing high payload capacity and extensive computerized controls.
Not ideal for: Those who require a lightweight, portable mount for frequent travel.
- Mount Type:German Equatorial
- Payload Capacity:55 lb
- Motor Type:High-Torque Servo Motors
- Drive System:Belt-Drive
- Hand Controller:NexStar+

Our verdict“This mount excels in power and control, making it ideal for serious astrophotographers with large setups, but less suitable for those seeking portability.”
How We Picked
Our selection process focused on belt drive equatorial mounts that balance precision, portability, and capacity. We prioritized models with proven tracking accuracy, user-friendly controls, and compatibility with astrophotography accessories. The two picks represent different user profiles: one optimized for lightweight, mobile setups, and the other for high-capacity, control-rich astrophotography. We compared specs, build quality, reviews, and feature sets to ensure each offers distinct advantages and tradeoffs.
Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
When selecting an equatorial mount with a belt drive system, consider what matters most to your astronomy pursuits. Portability, payload capacity, control features, and ease of setup all influence the best choice. Belt drives improve tracking smoothness and accuracy, especially during long astrophotography sessions, but they come in different configurations and capabilities that cater to different user needs.
Portability vs. Power
If you frequently travel or prefer a lightweight setup, the MirroSky GX35 offers excellent portability, but it sacrifices some payload capacity. Conversely, the Celestron CGX provides substantial power to support larger telescopes but is heavier and less convenient for quick moves. Decide whether mobility or maximum payload is your priority.
Control and Automation
Advanced computerized controls, like those in the Celestron CGX, can greatly simplify star alignment and object tracking, especially for long exposures. The MirroSky’s app control is more straightforward but might lack the depth of features needed for complex imaging. Your experience level with automation will influence which features are most beneficial.
Setup Complexity
Beginners might find the MirroSky GX35’s setup more manageable due to its integrated guidescope and simplified control options, while the Celestron CGX’s extensive features require more time and familiarity. Consider your comfort with mount calibration and software integration when choosing.
Frequently Asked Questions
What is a belt drive system on an equatorial mount?
A belt drive system uses flexible belts to connect motors to gears, providing smoother, quieter, and more precise movement compared to traditional gear systems. This setup reduces backlash and enhances tracking accuracy, which is especially important in astrophotography involving long exposures.
Are belt drive systems suitable for astrophotography?
Yes, belt drive systems are highly regarded in astrophotography because they support smoother and more accurate tracking, minimizing image blur during long exposures. They tend to produce less gear backlash and vibrations, resulting in sharper images.
How important is payload capacity in choosing an equatorial mount?
Payload capacity determines how much weight your mount can support safely. It’s critical to match this with your telescope and accessories; exceeding it can cause tracking issues or damage. For astrophotography, a higher capacity provides more flexibility to add equipment without compromising stability.
Can I upgrade my mount’s belt drive system later?
In some cases, yes, but it depends on the mount’s design and compatibility. Many mounts have modular parts or aftermarket upgrades, but it’s best to consult the manufacturer or a professional technician to ensure compatibility and maintain performance.
Is a computerized mount necessary for astrophotography?
While not strictly necessary, computerized mounts greatly simplify star alignment and tracking, especially for long exposures. They save time and improve accuracy, which can be crucial for high-quality astrophotography, making them a worthwhile investment for most serious amateurs.
Conclusion
If portability and ease of use are your top priorities, the MirroSky GX35 offers a compelling balance of features suitable for advanced amateurs who travel or prefer a lightweight setup. For those pushing toward serious astrophotography with larger telescopes, the Celestron CGX provides unmatched payload capacity and sophisticated control features, though at the expense of weight and complexity. Your choice hinges on whether you need mobility or maximum power and automation in your mount system.
