Off Axis Guider with 43mm. free opening.

  • ideal for all telescopes with short back focus or for flattener / corrector combinations
  • large aperture, 43mm.
  • very versatile due to a wide variety of adaptation options on both sides
  • off-axis port can be focused independently from the main camera
  • the prism’s position can be shifted – for a wider field to find guiding stars

Guiding using an off-axis-guider has many advantages. You do not need a guiding scope (= less load for the mount) and guiding accuracy increases because there’s no bending between main and guiding scope. Additional errors like mirror shifts are corrected, too.
