• Thread for Eliminating Light
The interference of stray light is effectively reduced, which not only improves the brightness of the image, but also effectively reduces the formation of dark edge and makes the edge details of the image clearer.

Features

• View of 45-Degree
• Standard 2 " diameter
• Prism clear aperture: 31mm
• Entirely machined aluminum
• 2"-1.25" adapter with brass compression rings
• Image erecting BAK4 prism with anti-reflection coating

• Precision Prism
Image erecting BAK4 prism with anti-reflection coating, high quality optical prism inside rather than a mirror which makes your image clear and sharp. As optical quality here is critical, you should really use a high-quality prism. High accuracy and high light reflection prism, good for astronomical viewing, you can get a real original image.

• Anti-reflection Coating
Internally matte blackened and threaded for no internal stray light reflection. The interference of stray light is effectively reduced, which not only improves the brightness of the image, but also effectively reduces the formation of dark edge and makes the edge details of the image clearer.

• Correct Upside Down Image
This wide 90 degree angle makes you view correct image from telescope stand,makes it easier to observe.
