Baader Amici Prism

An Amici prism diagonal provides a correctly oriented, non-reversed image, which is particularly useful for terrestrial viewing or when you want the view through your telescope to match a star chart directly. While mirror diagonals are often preferred for pure deep-sky astronomy to avoid potential light scatter, this high-quality Amici prism is designed to minimize those artifacts while offering the convenience of upright viewing.

Yes, this diagonal is designed specifically for telescopes with a standard 2-inch focuser drawtube. It slides directly into the focuser, allowing you to use 2-inch eyepieces or accessories.

The Clicklock system uses a rotating collar mechanism that clamps down evenly around the entire barrel of your eyepiece, rather than a single thumbscrew that can scratch or mar the barrel. It provides a much more secure, centered hold and is significantly easier to operate, especially when you are wearing gloves in the dark.

Yes, but you will need a separate 2-inch to 1.25-inch adapter, as this unit is natively sized for 2-inch accessories. Many astronomers keep a high-quality reducer adapter on hand for this exact purpose.

While Amici prisms are excellent for general use and terrestrial viewing, some observers find that at extremely high magnifications, a high-quality dielectric mirror diagonal might offer slightly better contrast. However, the Baader Deluxe model is engineered to high optical standards and performs very well for most amateur planetary and lunar observation.
