Spencer Pablo explained at Alphauniverse what gear he is using to shoot the US Eclipse. Check it out! He also has a nice advice:
If you find that you’re getting hung up on your gear and the eclipse is seconds away, stop. Use those solar glasses and enjoy the show with your own (protected) eyeballs. It’s better to experience the eclipse than it is to get frustrated trying to photograph it and missing the entire event.
Yes please…don’t forget to enjoy the moment 🙂
There is also a long list of tutorials on that special Bhphoto eclipse page.
