iOptron Mount CEM70 EC2W iPolar (76359)

The iOptron CEM70 series introduces a new standard in medium payload equatorial mounts, offering advanced features and portability for both visual observation and astrophotography. Building on the success of the CEM60, the CEM70 mounts retain the center-balanced design for natural stability while delivering precise GOTO pointing and accurate tracking. Compact yet powerful, these mounts are ideal for astronomers seeking efficiency and portability in their imaging setups.

Advantages at a Glance:

• Center-Balanced Design: Ensures maximum payload stability and efficiency.

• Payload Capacity: Supports up to 70 lbs (31.8 kg) with a mount weight of only 30 lbs (13.6 kg).

• Reliable Gear Clutches: Easy to use with large levers suitable for gloved operation.

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

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

• iPolar Electronic Polar Scope: Provides accurate polar alignment, even when the Pole Star is obscured.

• 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).

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

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

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

• Advanced Cable Management System: Internal cable routing prevents tangling and supports 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 features high-resolution encoders for sub-arcsecond tracking accuracy (<0.07 arcseconds), eliminating the need for guiding during astrophotography sessions.
