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, weighing just 8.8 pounds, which makes it highly portable for field use or travel. Its belt drive system, combined with worm gears, ensures smooth and precise movement in right ascension (RA) and declination (Dec). The inclusion of a 53mm ED guidescope and guide camera makes it an attractive option for those interested in astrophotography, especially with its companion MirroSky app, which simplifies control via iOS and Android devices. However, reliance on smart features and app connectivity may pose a learning curve for some users, and its lightweight construction could limit support for very heavy payloads. Compared with larger mounts, this model prioritizes ease of setup and mobility but sacrifices some of the capacity found in heavier, more complex mounts.
Pros:- Extremely lightweight and portable at just 8.8 lbs
- Includes guide-scope and guide camera for immediate astrophotography engagement
- Smart app control simplifies operation and monitoring
- Smooth movement thanks to belt and worm gear system
Cons:- Smart features depend heavily on app stability and may have a learning curve
- Limited payload support for heavier setups
- Build quality optimized for portability, less for rugged field conditions
Best for: Beginners, amateurs, or anyone needing a portable setup for quick star observations or light astrophotography.
Not ideal for: Heavy astrophotography setups or users who prefer traditional, manual operation without reliance on smart tech.
- Weight:8.8 lbs (4 kg)
- Guide-Scope:53mm ED
- Drive System:Worm gear and synchronous belt drives
- Included Accessories:Guide-scope, guide camera, mount
- App Compatibility:iOS and Android

Our verdict“This mount is perfect for beginners and travelers who want a lightweight, tech-enabled equatorial mount with belt drives.”
Celestron CGX Computerized German Equatorial Mount & Tripod, 55 lb Payload
The Celestron CGX is designed for astrophotographers who need a powerful, reliable mount. Supporting up to 55 pounds, it features a belt-drive system paired with high-torque servo motors, ensuring precise, smooth tracking even during long exposures. Its integrated NexStar+ computer controller offers a database of 40,000 objects, guided tours, and compatibility with various accessories. The tradeoff is its weight and setup complexity; the sturdy tripod and mount are quite bulky, making transport more challenging. While the advanced electronics and high capacity make it ideal for demanding imaging projects, the learning curve can be steep for beginners unfamiliar with computerized mounts. Compared to the lightweight MirroSky, the CGX emphasizes stability and capacity at the expense of portability.
Pros:- Supports up to 55 pounds, suitable for large telescopes
- Advanced computerized features with extensive object database
- High-torque servo motors for excellent tracking accuracy
- Built-in guided tours and user-friendly hand controller
Cons:- Heavy and bulky, less portable
- More complex setup process for newcomers
- Higher price point compared to simpler mounts
Best for: Experienced astronomers and astrophotographers seeking high payload and advanced features for deep-sky imaging.
Not ideal for: Beginners or those needing a lightweight, portable mount for quick setup and casual stargazing.
- Mount Type:German Equatorial
- Payload Capacity:55 lb
- Motor Type:High-Torque Servo Motors
- Drive System:Belt-Drive

Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
Choosing the right equatorial mount with a belt drive system involves balancing portability, capacity, automation, and budget. Belt drives offer quieter, more precise tracking and less backlash, which are critical for astrophotography and long-exposure imaging. Your decision should be guided by your experience level, intended use, and whether you prioritize lightweight design or high payload support. Here’s what to consider before making your purchase.
Portability vs. Power
If you need a mount that you can easily carry into the field or travel with, a lightweight model like the MirroSky GX35 is ideal. It sacrifices some payload capacity but offers quick setup and smart control features. Conversely, if you plan to mount large telescopes for serious astrophotography, a heavier, more robust mount like the Celestron CGX provides stability and high capacity, though at the cost of size and weight.
Automation and Control
Smart mounts with app control, such as the MirroSky GX35, simplify operation for beginners and casual users, combining tracking with guided control. More advanced mounts like the Celestron CGX include comprehensive computerized systems with extensive object databases and guided tours, which are better suited for experienced astronomers seeking automation and precision in their imaging routines.
Build Quality and Durability
Lightweight mounts tend to use more plastics and less rugged materials, which might impact longevity in harsh conditions. Heavy-duty mounts incorporate metal components, offering greater stability and durability—key for astrophotographers capturing long exposures. Consider your typical environment and how much weight your setup entails when choosing.
Budget and Future Proofing
Entry-level mounts with belt drives tend to focus on affordability and ease of use, while high-end models with extensive features come at a higher cost. Consider your current needs and whether investing in a more advanced mount now will pay off later, especially if you plan to expand your astrophotography gear.
Frequently Asked Questions
What are the main advantages of belt drive systems in equatorial mounts?
Belt drive systems significantly reduce gear backlash, resulting in smoother and quieter tracking compared to traditional worm gears. This is especially beneficial for astrophotography, where precise, stable movement is crucial for long exposures. Belt drives also tend to have less maintenance and can provide more consistent performance over time.
Is a lightweight mount like the MirroSky GX35 suitable for astrophotography?
The MirroSky GX35 can support basic astrophotography thanks to its included guidescope and guide camera, but its lightweight design limits payload capacity and stability for larger, heavier telescopes. It works best for casual astrophotographers or those starting out with smaller setups and who prioritize portability and ease of use.
Can I upgrade a mount with belt drive to handle larger telescopes later?
Upgrading a mount’s capacity generally involves choosing a model designed for higher loads from the start. While some mounts are modular or compatible with larger scopes, most belt drive mounts are optimized for specific weight ranges. It’s best to select a mount with a suitable payload capacity from the outset if you anticipate future expansion.
How important is the computer control feature on mounts like the Celestron CGX?
Computer control features streamline the process of locating and tracking celestial objects, reducing manual effort and increasing accuracy. For astrophotographers, these features are invaluable for long exposures and complex imaging routines. However, they also add complexity and cost, so weigh how much automation aligns with your experience level and needs.
What should I consider when choosing between a portable and a heavy-duty equatorial mount?
If portability is a priority, lightweight mounts like the GX35 are preferable, but they may have limited payloads and fewer advanced features. Heavy-duty mounts like the CGX offer greater stability and support for larger telescopes, ideal for serious imaging, but require more effort to transport and set up. Choose based on your primary use case, travel frequency, and willingness to handle heavier equipment.
Conclusion
For beginners and casual stargazers, the MirroSky GX35 offers an excellent balance of portability, smart features, and belt-driven precision, making it a great first choice. Serious astrophotographers who need to support large telescopes and demand advanced automation should look toward the Celestron CGX, despite its weight and complexity. Ultimately, your selection depends on whether you prioritize mobility and ease of use or high capacity and professional-grade features.
