The center-balanced equatorial mount iOptron CEM70 EC is designed for astronomy and astrophotography enthusiasts looking for a high-performance, stable and relatively portable solution. Its innovative Center-Balanced Equatorial Mount architecture reduces vibrations and enables precise tracking of celestial objects, even at long exposures. Thanks to its high load-to-weight ratio and Go2Nova® control, this mount is the ideal choice for observing and imaging nebulae, galaxies and star clusters with maximum sharpness.
Visit CEM70 EC is distinguished by :
| Features | Detail |
|---|---|
| Type | Center-balanced equatorial mount (CEM) |
| Payload | 31.8 kg (70 lb) |
| Frame weight | 13.6 kg (30 lb) |
| Load/weight ratio | 2,33 |
| Material | Aluminum alloy and steel |
| Latitude adjustment | 0° à 65° |
| Azimuth adjustment | ± 4° |
| Precision per step | 0,07″ |
| Periodic Correction (PEC) | Real-time EPSC < 0.3″ RMS |
| Controller | Go2Nova 8407+ V2, 40,000+ items |
| Polar alignment | iPolar integrated electronics |
| Saddle | Double Vixen/Losmandy |
Designed for demanding astrophotographers, the iOptron CEM70 EC offers an optimum balance between performance, portability and robustness. Its load-to-weight ratio allows heavy configurations to be carried without sacrificing stability, while precise tracking and real-time correction guarantee sharp images without star trails. The Go2Nova® interface facilitates celestial navigation, and electronic polar alignment considerably reduces set-up time.
| Criteria | CEM70 EC | CEM70 EC2 |
|---|---|---|
| Encoders | 1 high-resolution encoder (AD axis) | 2 high-resolution encoders (AD & DEC axes) |
| Periodic error correction | On a single axis (AD) in real time | On both axes (AD & DEC) in real time |
| Long exposure precision | Excellent | Optimal (greater resistance to imbalances) |
| Vibration resistance | High | Maximum (dual sensors) |
| Recommended use | Advanced astrophotography | Very long exposure astrophotography & deep imaging |
| Price guide | More affordable | Slightly higher |
In short, the CEM70 EC is a powerful choice for most astrophotography configurations, offering precise tracking and good value for money. The CEM70 EC2 gains in robustness and precision thanks to its dual encoder system, making it the mount of choice for extreme long exposure imaging projects or for astrophotographers seeking the best periodic error correction on both axes.
Center-balanced equatorial mount for astrophotography with an instrument weighing up to 31.8 kg (excluding counterweights): 11″ Schmidt-Cassegrain, 130–150 mm refractors. Portable (13.6 kg head). Recommended capacity for astrophotography: 23.9 kg, or 75% of the advertised load capacity, to ensure precise tracking.
EMC design (load centered above the tripod): more stable and lighter than a conventional German equatorial mount with the same capacity. Built-in iPolar, GPS, and USB port. EC version: high-resolution encoder on the AD axis to significantly reduce periodic error.
Yes, like any German equatorial mount. The iOptron CEM70 EC comes with 1 × 9.5 kg counterweight and a bar (Ø 28 × 415 mm).
The iOptron CEM70 EC is powered by 12 V DC, 5 A; a power adapter is included. Power consumption: 0.6 A during tracking, 0.8 A during GoTo. The power supply is included. The included AC adapter is intended for indoor use; in the field, use a 12 V battery.
The iOptron CEM70 EC is sold without a tripod. Choose a tripod or column that can support the total load.
The iOptron CEM70 EC can be controlled using a hand controller or a computer via USB (ASCOM). For autoguiding (ST4 port), a guide scope such as the 52 Scope guide or the Sky-Watcher EVOGUIDE-50ED is appropriate.
