JMI Event Horizon Robotic Pegasus FocusCube3 Telescope Focuser - Newtonian Base

The name is a mouthful  - what it means is that we've made an adaptation to mount the Pegasus FocusCube3 focus motor on our Crayford Focuser that will then mount on a Newtonian telescope tube.  We provide the focuser mechanics and you provide your Pegasus FocusCube 3 focus motor.  Your motor mounts on our focuser with screws and the couplers already included with the Pegasus FocusCube 3 focuser kit you bought.

  • Control focus from Pegasus software and ASCOM interfaces
  • Autofocus using popular software (NINA, Sequence Generator Pro, etc)
  • ZERO image shift
  • Friction drive for backlash free focusing
  • CNC Machined Crayford Design
  • Draw tube length of travel is configurable at the time of purcase (see drop down menu)
  • Compatible with Newtonian telescope tubes from 7.25″ diameter or larger as well as flat focuser boards
  • Weight: 1.4 pounds
  • Load Capacity: 8 pounds
  • Individually assembled and tested in our own facility
  • 100% Made in USA

Note: Fitting a new focuser onto an existing telescope takes careful consideration and engineering.  This is not a one size fits all solution.  There are many publicly available software tools available to help with this, have a look around on the internet forums for more guidance.

Optional Optical Adapters:

  • 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.
