90° Amici Erecting Prism with 2” Eyepiece and 2” Barrel

The Baader 90° Amici Erecting Prism is designed to provide high-quality terrestrial viewing with 2″ eyepieces. It features a 2″ barrel and includes a reduction from 2″ to 1¼” for added versatility. This prism is ideal for low to medium magnification, offering an erect, non-reversed image that ensures a comfortable viewing experience. The multi-coated (MC) optics enhance light transmission for clear, bright images. It’s perfect for terrestrial use but not recommended for high magnification, where mirrors and specialized prisms provide superior results for astronomical viewing.

Key Features:

• 90° Deflection Angle: The 90° deflection provides comfortable viewing, especially for terrestrial observations, with an erect, non-reversed image orientation.
• Multi-Coated Optics: The prism features high-quality, multi-coated (MC) optics, ensuring enhanced light transmission and sharp, bright views.
• 38mm Clear Aperture: The 38mm clear aperture allows a wide field of view, making it ideal for terrestrial observations with minimal vignetting.
• Reduction from 2″ to 1¼”: Includes a reduction from 2″ to 1¼”, making it compatible with a range of eyepieces and accessories.
• Not Suitable for High Magnification: This prism is excellent for low and medium magnification, but for high magnification and better astronomical imaging, we recommend Baader’s mirrors and other specialized prisms.
• Optical Length: The optical length is 99mm with the 2″ barrel, and with the 1¼″ reducer, it adds an additional 10mm for optimal focus.
• Total Reflection Surface: The total reflection surface ensures minimal light loss for brighter, clearer images during viewing.
