- Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). 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.
- Universal Smartphone Adapter – To capture pictures of Objects seen in the binoculars (Terrestrial objects, Moon and planets) right in your smartphone immediately as you observe it.
