Just in case you’re one of the few people who haven’t heard yet – on Monday, August 21st, the U.S. is going to experience a total eclipse of the sun for the first time since 1979. Although it will take approximately 90 minutes for the moon to make its journey across the sun, the total eclipse will be visible for less than 3 minutes. If you want to capture this rare celestial sight, you’ll want to be well prepared!

Here are five videos that will provide you with background information and helpful tips to photograph the eclipse.

WARNING! Remember to protect your eyes and camera lens when observing or photographing a partial eclipse by wearing solar eclipse glasses and using a solar filter for your camera lens. The only time it is safe to look directly at an eclipse is when the moon is completely positioned in front of the sun. Staring at the sun before or after can result in damage to your eyes and camera.
