iOptron Mount CEM70 EC2N-NUC iPolar (76348)

The iOptron CEM70 series represents a new standard in medium payload equatorial mounts, offering advanced features and streamlined components for efficient, accurate, and portable imaging setups. Building on the success of the CEM60, the CEM70 series delivers precise GOTO pointing, accurate tracking, and innovative operational utilities tailored to the needs of both observers and astrophotographers. With a payload capacity of 70 lbs (31.8 kg) and a mount weight of only 30 lbs (13.6 kg), it combines portability with high performance.

Key Features:

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

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

• 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 objects.

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

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

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

• Advanced Cable Management System: Prevents tangling and supports internal connections for mount, iPolar, guider, and camera.

• Easy Lock Drive Gear Engagement: Large levers for convenient operation, even with gloves.

• Spring-Loaded Dual Saddle: Compatible with both Losmandy and Vixen-style dovetails.

The CEM70EC variant includes high-resolution encoders for sub-arcsecond tracking accuracy (<0.25 arcseconds) without requiring guiding during astrophotography sessions. The mount also supports seamless integration with an Intel® NUC mini-computer (38mm thickness), enhancing its functionality for advanced imaging setups.
