JMI Event Horizon Robotic Telescope Focuser - Newtonian
Building on the excellent base of our Event Horizon focuser, we spent several years perfecting its transformation into a completely robotic version for astro-imaging. This version of our focuser features an integrated high precision motor and control system that gives 8.1x10-6 inch (.2 micron) focus step position precision. We deliver 10 times finer control than comparable focusers.
In addition to fine motor control with position feedback it is ASCOM compatible and can be controlled with many of the popular astro-imaging software packages that you may already own. The system comes with easy-to-install drivers for instant connectivity.
This focuser is designed to mount on Newtonian telescope tubes and will require careful consideration and engineering for mounting. This is not a one size fits all solution. The focuser gives 1/2″ of travel. Weight is 1.4 pounds without the controller.
Comes with a USB stick with the ASCOM driver and instructions.
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 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.
