Omegon Amici prism 45° 1.25 inches

Omegon Amici prism 45° 1.25 inches sets the image upright and left-right correctly, exactly as you see it with the naked eye. This makes this 45° Amici prism perfect for daytime bird watching, ship tracking or landscape viewing through your telescope, without having to “flip” your brain. The 45° viewing angle ensures a relaxed posture, especially during longer sessions.

The prism has a 1.25-inch input and output, so you can directly attach it to most refractors, Maksutovs, and Schmidt-Cassegrains and use your existing 1.25’ eyepieces. Are you looking for a star diagonal for high magnifications? Be aware that an Amici prism can sometimes show a fine diffraction line on bright stars; for Moon/planets at high magnification, a standard diagonal is the better choice. For terrestrial use, an Amici is the standard because the orientation is natural.

Observation goals

Use this Amici prism primarily for terrestrial and low-magnification observations: nature, shipping, horizon objects and a straight-up moon image. For serious planetary detail and deep-sky at high magnification, a regular star diagonal remains more appropriate.
