Sun 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 buildup can damage the optic and any attachments attached to it.
Never leave your optic unattended. Make sure that an adult who is familiar with proper operating procedures is with your optic at all times, especially when children are present.
