Approximate focus settings of the 50/200 Omegon Guide Scope  on a ZWSO ASI120MM

  1. Fix the included 22mm 1.25" extender to the camera  
  2. Insert the camera into the 1.25" eyepiece holder of the guide scope until the black of the extender is fully inserted (and no longer visible), but the red shaft of the guide camera is still fully visible.
  3. For a good start set:
    • the coarse focus to 2.0 
    • and the microspeed fine focus to 2.25
