I did take a few pictures of the eclipse, but I didn't put much thought into it. Using the camera was actually a bit of an afterthought. I attached my 70-400 mm only to use it as a telescope to see better. Huh. This telescope takes pictures, too? Great idea.
Since I hadn't prepared for photographing, I ended up putting my camera on 16000 ISO (yes, that's three 0s), 1/60 sec at 5.6. (Yes, these photos were taken without a tripod--handheld in the complete dark.) I love my 70-400 mm. That is a fantastic lens, even if it weighs 3.5-4 pounds (yes, that's pounds, people. Sheesh. Just believe me).
These photos aren't edited much from the original. I wish I'd taken some time to set up the tripod, think about ISO noise, and exposure. I think I could have snapped some phenomenal shots.
Then again, I wasn't too thrilled to be up in the middle of the night to begin with.
