JMI Event Horizon Robotic ZWO EAF Telescope Focuser - Cassegrain  

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

No more mirror image shift while trying to focus your astrophotos and you can control your focus from ASI AIR. 

Compatible with 6″ to 16″ Cassegrain telescopes (e.g. SCT and Mak-Cas) with standard output threads. The focuser gives 1/2″ of travel and is designed for fine focus after rough adjustment with the normal telescope focusing knob. Weight is 1.4 pounds without the controller.

Comes with no optical adapters so that you can select the optional adapter(s) you need, if any.

Select JMI Combination 1.25-inch Eyepiece and T-Thread Adapter, ADPT2-1.25T for camera use. JMI Adapter for mounting a CCD or other camera, with a standard T-thread, into a 2" drawtube. It also doubles as a 1.25" adapter. A T-adapter holds a CCD camera more securely than a standard 1.25" adapter. The adapter uses a compression ring to secure inserted equipment. It includes standard 48mm filter threads on the other end of the adapter (inserted into focuser end).

Select Lumicon 2 Inch Male - SCT Male Adapter, LA1060 to attach SCT threaded accessories. Lumicon 2 Inch Male - SCT Male Adapter drops into 2″ telescope eyepiece holders and presents male SCT threads (2″ x 24 tpi) for Schmidt-Cassegrain telescope accessory attachment (SCT diagonal, for example). Includes 2″/48mm filter threads.

Select Farpoint 2 Inch Focuser to 1.25 Inch Eyepiece Adapter, FAV100 for a visual 2" to 1.25" eyepiece adapter. Farpoint 2 Inch Focuser to 1.25 Inch Eyepiece Adapter features a non-marring compression ring for precise centering of telescope eyepieces. Threaded for both 2 inch and 1.25 inch filters and has a stop to prevent long eyepieces from damaging filters.
