⚠️ IMPORTANT – Solar Observation Safety

Observing the Sun without a certified solar filter is extremely dangerous and can cause permanent eye damage.

Never point the telescope at the Sun without a proper front-mounted solar filter

Always inspect the filter material for damage before use

Do not use if the filter is scratched, torn, or loose

Ensure the filter holder is fully secured before solar observation
