YSK if you are watching the solar eclipse Monday, don't take a photo with your cell phone. It can burn the sensor and you wont be able to use it anymore. Same for professional cameras without the proper equipment.

Apart from not being able to zoom in enough for a good shot, unless its totally eclipsed it will burn the sensor rendering it unusable. Even more devastating if you use a real canera due to price. A shade 14 welding filter will do the trick though.
