ZWO Temperature sensor for EAF focusing motor

ZWO Temperature Sensor for EAF: focus that moves with the night

When the temperature drops at night, your telescope tube contracts and the perfect focus shifts. This temperature sensor provides the ZWO EAF with the information to automatically compensate for that, so your focus stays stable during long imaging sessions and changing conditions.

You connect the sensor directly to the EAF. Please note: you use either this sensor or the hand controller, not both at the same time.

Features

• Automatic focus compensation for temperature changes
• Prevents focus drift caused by cooling optics
• Direct connection to the ZWO EAF
• Compact and without external power supply

Compatibility

Exclusively for the ZWO EAF focuser. Cannot be used simultaneously with the EAF hand controller.

Specifications

A small accessory that the motor focus of ZWO keeps you sharp all night.
