For terrestrial or astronomical use, this diagonal produces a right-side-up, non-reversed image with correct daytime orientation 
  • Fully coated prisms for superior image fidelity and maximum light throughput
  • Accepts 1.25" eyepieces, fits in 1.25" focusers
  • Not recommended for use in Newtonian reflector or Dobsonian reflector telescopes
  • Requires 5/8" more focus travel than typical star diagonals

For terrestrial viewing with a refractor or Maksutov-Cassegrain telescope, use of a correct-image (or image erecting) prism telescope diagonal may be desirable. The image through the eyepiece will appear upright and non-reversed, matching naked-eye orientation. This makes a correct-image telescope diagonal essential for comfortable terrestrial viewing with the above telescope types. The diagonal is also useful for astronomical viewing for those that prefer to have the view through the telescope match the naked-eye orientation. This telescope diagonal is fully multi-coated for maximum light transmission and is threaded for use with 1.25" eyepiece filters.

Note that the 45° Orion Correct-Image Prism Diagonal requires 5/8" more focus travel than typical diagonals.

Diagonals are not suitable for use with Newtonian reflector telescopes due to insufficient focus travel.
