Item #  07216

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 recommended for use in reflector telescopes.

When viewing earthly sights, the 45 degree diagonal truly makes life more comfortable. This diagonal is well worth the small expense. There is no perceptible change in optics compared to my (more expensive) dielectric 90 degree diagonal because in daylight, the distances are so much shorter and images are so much brighter. (I don't use this at night). Even for occasional use, I consider this a must-have accessory.
Pros: saves your neck and back, correctly orients the view
Cons: none
Yes, I recommend this product!
