How can I photograph a total solar eclipse?
You will need to purchase a solar filter that will reduce the brightness of the sun so that the light intensity does not destroy your camera. If you ONLY take a photo at the moment of totality, you will not need this filter, and will be rewarded by being able to photograph the faint corona, which will not be visible if you have the filter in place. Most digital cameras with telephoto lenses of 100 mm or larger will show a disk for the eclipse that will show some detail. As a trial, photograph the full moon at night. It will be the same diameter as the total eclipse, so you can practice on the moon first to get the right telephoto lens combination. There are many places on the internet where you can get detailed information such as Mr. Eclipse http://www.mreclipse.com/SEphoto/SEphoto.html
