iOptron Mount CEM70 ECW iPolar (76347)

The iOptron CEM70 series introduces a new generation of center-balanced equatorial mounts, designed for both visual observation and astrophotography. With a payload capacity of 70 lbs (31.8 kg) and a mount weight of just 30 lbs (13.6 kg), these mounts offer an excellent balance of portability and performance. The center-balanced design ensures natural stability, making the CEM70 series ideal for astronomers seeking precision and efficiency in their setups.

Key Advantages:

• Center-Balanced Design: Provides maximum payload stability with natural balance.

• Payload Capacity: Supports up to 70 lbs (31.8 kg) with a lightweight mount head.

• Reliable Gear Clutches: Easy to operate, even while wearing gloves.

• Precision Adjustments: Altitude and azimuth adjustments for accurate polar alignment.

• Stepper Motors: Offer 0.07 arcsecond accuracy for precise GOTO and tracking.

• iPolar Electronic Polar Scope: Ensures accurate polar alignment, even when the Pole Star is not visible.

• Go2Nova® 8410 Controller: Features advanced GOTONOVA® technology, a built-in heater, and a library of 212,000 celestial objects.

• High Precision Tracking: Low periodic error (<0.3 arcseconds rms) with real-time periodic error correction (RPEC).

• Built-in GPS: 32-channel system for precise location tracking.

• USB 3.0 Connection: Ensures high-speed data transfer for imaging setups.

• ST-4 Autoguiding Port: Seamless integration with guiding systems.

• Advanced Cable Management System: Internal routing prevents tangling and accommodates connections for mount, iPolar, guider, and camera.

• Dual Saddle: Spring-loaded 8" saddle compatible with Losmandy and Vixen dovetails.

• Built-in Wi-Fi Connectivity: Enables remote operation.

The CEM70EC variant includes high-resolution encoders for sub-arcsecond tracking accuracy (<0.07 arcseconds), eliminating the need for guiding during astrophotography.
