MirroSky by Spectrum Optical GX35 Smart EQ Mount with Guide-Scope
The MirroSky GX35 targets astronomers who prioritize mobility and integrated imaging features. Its lightweight design—just 8.8 pounds—makes it ideal for travel or quick setups, yet it doesn’t compromise on tracking accuracy thanks to the worm gear and belt-drive system. The inclusion of a 53mm guidescope with a built-in guide camera simplifies deep space imaging, and the MirroSky app allows control via iOS or Android, making it accessible for users at various skill levels. However, the limited payload capacity and additional accessories needed for full setups may restrict heavier equipment and more complex imaging sessions.
Pros:- Very lightweight and portable
- Integrated guidescope and imaging camera
- Supports precise tracking with belt drives
- Compatible with MirroSky app for easy control
Cons:- Limited payload capacity for heavy gear
- Setup can be complex for beginners
- Additional accessories may be required for advanced imaging
Best for: Amateur astronomers and astrophotographers who value portability, ease of use, and integrated guidescopes.
Not ideal for: Users with heavy equipment needs or those who prefer a stationary, high-power mount for large telescopes.
- 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
- Camera Sensor:Sony IMX662 CMOS (2.1 MP, 1/2.8″)
- Mount Modes:Equatorial and Alt-Az
Our verdict“This mount stands out for mobile deep space imaging, blending portability with reliable tracking, but it’s less suited for heavy-duty setups.”
How We Picked
Our selection process focused on mounts that incorporate belt drive systems to ensure smooth, precise tracking essential for astrophotography. We evaluated models based on payload capacity, build quality, control features, portability, and user complexity. The top picks balance these factors, with the Celestron CGX representing a high-power, feature-rich option suited for advanced users, while the MirroSky GX35 offers a lightweight, mobile solution that still delivers reliable tracking and imaging capabilities.
Factors to Consider When Choosing Equatorial Mounts With Belt Drive Systems
When selecting an equatorial mount with a belt drive system, your main considerations should include payload capacity, portability, control features, and the complexity of setup. Belt drives significantly improve tracking smoothness and accuracy, which is vital for astrophotography. The decision hinges on whether you need a robust, feature-rich mount for heavy setups or a lightweight, portable option that still delivers precise tracking for deep space imaging.
Payload Capacity and Mount Power
Assess your telescope and accessories’ weight to ensure the mount can handle your entire setup comfortably. The Celestron CGX offers a high payload capacity suitable for large telescopes, making it ideal for serious astrophotography. In contrast, the MirroSky GX35 is better suited for lightweight setups, offering enough support for smaller telescopes and guidescopes but limiting heavy gear.
Portability and Size
If you frequently travel or set up in different locations, portability becomes a key concern. The GX35’s lightweight design makes it easy to carry and quick to set up, whereas the CGX’s heavier, more complex frame is better suited for permanent or semi-permanent observatories where power and space are less constrained.
Control and Ease of Use
The CGX provides extensive computerized control, ideal for users who want advanced features and large object databases. The MirroSky app compatibility on the GX35 makes it accessible for users who prefer smartphone control and quick setup, though it may require some familiarity with app-based controls.
Frequently Asked Questions
What is belt drive technology in equatorial mounts?
Belt drive technology uses belts instead of traditional gear teeth to transmit motion from the motors to the mount. This design reduces gear backlash, results in smoother tracking, and minimizes vibrations, which are critical benefits for astrophotography. Belt drives also tend to operate more quietly and with less wear over time compared to standard gear systems.
Are belt drive equatorial mounts suitable for astrophotography?
Yes, belt drive equatorial mounts are highly recommended for astrophotography because they provide more stable and precise tracking, especially during long exposures. The belt drive minimizes gear backlash and vibrations, leading to sharper images. However, the overall suitability also depends on the mount’s payload capacity and control features.
How important is payload capacity when choosing an equatorial mount?
Payload capacity is a critical factor because it determines whether the mount can support your telescope, camera, guidescopes, and other accessories safely and effectively. An underpowered mount can cause tracking issues and vibrations, degrading image quality. For heavier setups, a mount like the Celestron CGX with higher capacity is essential, whereas for lighter gear, a smaller mount like the GX35 suffices.
Is portability a major consideration with belt drive mounts?
Portability is often a tradeoff with performance. The lightweight MirroSky GX35 excels here, making it easy to transport and set up quickly. Conversely, larger mounts with higher payloads, such as the CGX, tend to be bulkier and less portable but provide more power and stability for demanding setups. Your choice depends on whether you prioritize mobility or power.
What are the setup complexities associated with belt drive mounts?
Many belt drive mounts, especially those aimed at advanced users, can involve a more intricate setup process. The CGX’s advanced features may require more time to configure and calibrate, especially for beginners. The GX35, while more portable, still needs proper alignment and guidescope setup, which might pose a challenge for newcomers but remains manageable with instructions and some practice.
Conclusion
For those investing in serious astrophotography with large telescopes and advanced control needs, the Celestron CGX offers unmatched power and features, though it demands more space and setup effort. Conversely, the MirroSky GX35 makes a compelling choice for amateur astronomers and mobile users who want reliable tracking in a lightweight form factor, even if it means limiting the weight of their equipment. Your decision should hinge on whether your priority is high-capacity, advanced control, or portability and ease of use.
