Omegon Amici prism 90° 1.25 inches

Omegon Amici prism 90° 1.25 inch fully corrects the image: upright as well as left-right correct. Where an ordinary star diagonal leaves the image mirrored, this Amici prism gives you a true-to-life image as seen with the naked eye. That makes it particularly suitable for daytime use, such as bird watching, boating and landscapes.

The 90° viewing angle makes this prism comfortable for extended use, especially when objects are high in the sky or when you want to maintain an upright sitting position during terrestrial observation. The standard 1.25” connection allows you to use it with virtually all refractors, Maksutovs and Schmidt-Cassegrains, in combination with all your 1.25” eyepieces.

For astronomical use, this prism works well at low to medium magnifications, for example to view the moon or star fields in a naturally oriented view. However, keep in mind that at high magnifications on bright stars, an Amici prism can cause diffraction spikes. For detailed planetary observations, therefore, a classic star diagonal remains more suitable.

Application

Ideal for nature observation, bird watching and boating. Also suitable for the moon and wide star fields, where an upright view is useful. For deep-sky objects and high magnifications, a regular diagonal is the better choice.
