    Solar Warning
    • Never look directly at the Sun with the naked eye or with this optic. Permanent and irreversible eye damage may result.
    • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
    • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.

  • ED objective lenses provide superior images virtually free of chromatic aberration with accurate color reproduction, increased resolution and contrast

  • Fully multi-coated optics for maximum light transmission through the optical path

  • Phase and dielectric coated BaK-4 prisms for vivid, true-to-life colors

  • Wide field of view and 8.2' close focus

  • Tripod adaptable
