JMI Event Horizon Robotic ZWO EAF Telescope Focuser - Cassegrain Base

The name is a mouthful  - what it means is that we've made an adaptation to mount the ZWO EAF focus motor on our Crayford Focuser that will then mount onto the rear of your Schmidt Cassegrain Telescope via the standard SCT threads.  We provide the focuser mechanics and you provide your ZWO EAF focus motor.  Your motor mounts to our focuser with two screws and the couplers already included with the ZWO focuser you bought.

Take the frustration our of focusing your SCT type telescope!
