Baader T-2 Amici Prism Diagonal Body

Unlike standard star diagonals that flip the image mirror-style, an Amici prism diagonal provides an upright and laterally correct view. This makes it essential for terrestrial viewing, such as birdwatching or observing distant landmarks, where you want the image to match what you see with the naked eye.

No, this is the diagonal body and prism only. You will need to purchase the specific T-2 nosepieces and eyepiece holders separately to match your telescope's focuser and your preferred eyepiece barrel size.

Yes, the T-2 system is highly modular. By attaching the appropriate T-2 nosepieces and eyepiece holders, you can configure this diagonal to accept either 1.25-inch or 2-inch accessories, depending on your specific setup requirements.

The 31mm clear aperture is designed to minimize vignetting, ensuring that you get a bright, unobstructed view through your eyepiece. It is particularly beneficial when using long-focal-length eyepieces that have a wide field of view.

For pure deep-sky astronomy, a high-quality mirror diagonal is often preferred because it avoids the potential optical artifacts sometimes associated with prisms. However, the Amici prism is the superior choice if you frequently switch between terrestrial and astronomical observing and require a correctly oriented image.
