  • Comfortable observation with 90-degree: Look pleasantly from above into your eyepiece, filter thread for any 1.25" filter and accepts standard 1.25" eyepieces.
  • The prism gives you a bright and clear picture: The prism is made of genuine optically processed BK7 glass, high quality optical prism inside rather than a mirror which makes your image clear and sharp. The Amici prism looks as beautiful as binoculars, but you can zoom in much higher with your eyepieces.
  • Simply insert the erecting prism into the 1.25 "focuser and enjoy upright and right-angled images with your eyepieces - watch birds, deer at the edge of the forest, the summit cross on a mountain or a cruise ship far out on the sea.
  • The prism housing is made of precision molded ABS plastic and the barrels are made of metal - which ensures a tight fit and long grip. Use a clamping screw made of aluminum to fix your eyepiece.
