Sun Warning
Never look directly at the sun with the naked eye or with an optic (unless you have the proper sunscreen). Permanent and irreversible eye damage may result.
Never use the optics to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories connected to it.
Never leave the optics unattended. Ensure that an adult familiar with proper operating procedures is with your optic at all times, especially when children are present.
