SOLAR SAFETY

REMEMBER IT IS VERY UNWISE TO LOOK AT THE SUN unless you have the proper astronomical filters for the purpose. IT IS SAFER TO PROJECT THE SUN'S IMAGE ONTO A SCREEN. Never look through view finders at the sun. instead look at the shadow of the instrument on a card. When the shadow is as small as it can be it is pointing towards the sun. NEVER LOOK DIRECTLY AT THE SUN IT CAN BLIND YOU !
