William Optics 45°, 1.25″ on 1.25″ Amici prism

William Optics 45°, 1.25″ to 1.25″ Amici Erecting Prism: view just like you do with the naked eye

The William Optics 45-degree Amici prism shows the image exactly as it is in reality: upright and laterally correct. You point your telescope and instantly recognize what you see, making it great for beginners and indispensable for daytime nature observation.

The 45-degree viewing angle provides a relaxed posture, especially for objects low above the horizon. Inside is BaK-4 glass with an anti-reflective coating for a clear, high-contrast image, and the brass ring clamp holds your eyepiece securely without scratching.

Which telescopes

Suitable for refractors and catadioptric telescopes with a 1.25-inch connection. Not for Newtonians: the focal point is too close to the tube.

For whom yes and for whom no

• ✓ Nature observers who use their telescope as a spotting scope during the day
• ✓ Beginners who want to see the image as it is on the star chart
• Newton owners: a prism has no focus room there
