Security advise
Never look at or near the sun without a tested solar protection filter. The solar filter must be installed on the objective lens, not on the eyepiece lens! Because of the light beam, the filter film would be destroyed and eye damage or even complete blindness would be the consequence. Check the solar filter foil before each solar observation to ensure it is undamaged. Children must be under constant supervision and be instructed. Never leave the optics unattended. Take frequent breaks (every 3 minutes) when oberserving the sun. Do not look at the sun after an eye operation or other eye ailment. Make sure the self-made solar filter fits exactly and has safe hold. Do not expose the solar filter film to high temperatures for a long time.
Cleaning
Clean the foil only if it is absolutely neccessary! Small grains of dust do not disturb the sight in any way. For cleaning use a lint-free and soft cloth and moisten it with a little water. Then clean the foil very carefully and without pressure.
