Its belt-drive system, combined with high-torque servo motors, ensures highly precise tracking especially for long-exposure astrophotography. The mount’s support for up to 55 pounds makes it suitable for larger telescopes and imaging gear. Its NexStar+ hand controller with a database of 40,000 objects offers extensive automation, simplifying target acquisition for those who prefer automation over manual setup. Compared with the MirroSky, this mount is heavier and less portable, which might be a drawback if mobility is a priority. However, it excels in stability and automation, making it a strong choice for dedicated imaging setups. The main tradeoff is that it demands more initial setup time and some technical familiarity, especially for maximizing its features. This mount makes the most sense for users who want to handle larger equipment with minimal tracking issues over long sessions.
Pros:- Supports up to 55 lbs payload
- Belt-drive system for smooth, accurate tracking
- Automated object database with NexStar+ controller
- High-torque servo motors for precise movement
Cons:- Heavier and less portable
- Requires more complex setup and technical knowledge
- Potentially steep learning curve for beginners
Best for: Advanced astrophotographers and observers with heavy equipment and a preference for automation.

Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
Choosing the right equatorial mount with a belt drive system involves understanding your specific astrophotography goals and setup constraints. The key factors include payload capacity, portability, automation, and ease of use. Belt drive systems are prized for their ability to deliver smoother, more accurate tracking, especially over long exposures, but they often come at a higher price and complexity. Whether you prioritize a lightweight, portable system or need a mount capable of supporting larger telescopes and accessories, understanding the core differences helps ensure your investment matches your ambitions.
Portability vs. Payload Capacity
If you frequently shoot in the field or travel to dark-sky sites, portability becomes a priority. The MirroSky GX35 demonstrates that a lightweight design can still offer precise tracking and integrated guiding, making setup and transport easier. Conversely, if your focus is on imaging larger telescopes or multiple accessories, the Celestron CGX provides the essential payload support, though at the expense of weight and bulk. Your choice hinges on whether mobility or capacity matters more for your observing style.
Automation and Ease of Use
The Celestron CGX excels with its extensive object database and automated tracking, which makes it a good fit for users comfortable with more complex setups and looking for minimal manual adjustments. Meanwhile, the MirroSky’s app control offers modern convenience, especially for those who prefer smartphone or tablet interfaces. Beginners might lean toward the simpler, integrated system of the MirroSky, provided they’re okay with some setup complexity. Advanced users will appreciate the automation features of the CGX for long, hands-off sessions.
Price and Value
While the MirroSky GX35 tends to be more affordable and offers a good balance of features for its weight class, the Celestron CGX’s higher price reflects its heavier payload, automation, and advanced motors. Your budget will influence which features are most critical—those seeking a lightweight, portable mount with integrated guides will find the GX35 more appealing, whereas dedicated astrophotographers requiring support for larger setups will find the CGX’s capabilities justify its cost.
Frequently Asked Questions
What is a belt drive system in an equatorial mount?
A belt drive system in an equatorial mount uses belts instead of gears to transfer motor power to the axes, resulting in smoother and more precise tracking. This design reduces backlash and gear noise, which is especially beneficial for long-exposure astrophotography, as it minimizes tracking errors and vibrations that could blur images. Belt drives typically require higher initial investment but are favored for their performance benefits over traditional gear systems.
Are belt drive systems more complicated to maintain?
Compared to traditional gear systems, belt drives are generally lower maintenance because belts are less prone to wear and require less lubrication. However, they do need periodic inspection for tension and alignment, especially after transport or adjustments. Proper installation and tensioning are crucial to maintaining their smooth operation, which might be more technical for beginners but ultimately offers better long-term consistency.
Is a heavier mount always better for astrophotography?
Not necessarily. Heavier mounts like the Celestron CGX support larger payloads and can provide greater stability for long exposures, but they sacrifice portability and ease of transport. For mobile astrophotographers or those with limited setup space, lighter mounts such as the MirroSky GX35 may be more practical, even if their payload capacity is somewhat lower. The best choice depends on whether stability or mobility takes precedence for your observing style.
Can I upgrade the drive system in my mount later?
Upgrading the drive system in a mount is possible but not always straightforward. Belt drives are often integrated during manufacturing, and retrofitting an existing mount can be complex and costly. If you anticipate needing a belt drive for improved performance, it’s best to select a mount with this feature from the start. This ensures that the system is optimized for your astrophotography needs without risking compatibility issues or reduced performance.
What level of technical skill is needed to operate these mounts?
Both mounts require some level of technical skill, especially for initial setup and calibration. The MirroSky GX35’s app control simplifies operation once configured but may require familiarity with smartphone apps and guidescope alignment. The Celestron CGX offers extensive automation and software features, which can be overwhelming for beginners but become manageable with patience and reading the manual. Overall, a basic understanding of mount setup and alignment is recommended, with more advanced features suited to experienced users.
Conclusion
If you primarily need a lightweight, portable mount with integrated guidescope and app control, the MirroSky GX35 is the best choice. It caters well to astrophotographers on the go who want to keep their setup simple yet capable. For those who operate larger telescopes, require high payload capacity, and prefer automation, the Celestron CGX offers the stability and features necessary for serious deep-sky imaging. Your decision should hinge on whether mobility or raw support for heavy gear aligns with your observing priorities.
