Use your astronomy telescope for daytime terrestrial viewing!
Baader’s premium 1.25” 45-degree Amici prism diagonal gives correct-image views with refractors, Schmidt-Cassegrain, and Maksutov-Cassegrain telescopes with your standard astronomical eyepieces.
Compared to other erect-image diagonals, Baader’s 1.25” Amici prism diagonal uses a larger prism with a full 24mm clear aperture. This means you can use lower-magnification eyepieces without the effects of vignetting (darkening) around the edge of the field of view.
The Amici prism in this diagonal is fully multicoated to reduce stray reflections and maximize image brightness and contrast.
This Baader 1.25” 45-degree prism diagonal can also be used for basic astronomical viewing, but the Baader Astro-Grade Amici prism diagonal (Agena part# ODIA-BP-AMICI-DX1) is a better choice for those who seek the best possible correct-image view of celestial objects, especially at high magnification.
Eyepieces are held in place with a screw clamp with a single set screw.
Note: This diagonal is not intended for use with Newtonian reflecting telescopes because their focusers do not permit enough inward travel to bring an image to focus.
The diagonal weighs just 8.3 oz (234g).
Manufacturer part number: 2956150.
