shooting the eclipse

Any suggestions on ISO/f stop/shutter for shooting the upcoming eclipse with a 40d??

I think there is some good stuff here :

What Jean-Denis recommended is real good.

My advice--There is no one answer to your question. The difference between the umbral eclipse and the still uncovered (full light) moon is many many stops. And there are times when you can have both at the same time. During August's eclipse, I took photos at 1/1000th of a second and 4 seconds. There will be many times during the eclipse that your sensor simply does not have the dynamic range it needs to handle both the bright and dark areas.

At some points, you may want to get two different exposures--short for the brighter parts of the moon, long for the dimmer parts. Then you can put them together in Photoshop later.
Learn to use the histogram display on the back of your camera. Expose for a hump about a third of the way up on a full moon. That will be your first exposure (before the eclipse starts) and your fastest. As for F stop, go wherever your lens is sharpest.


You do not need a guided or even driven scope, but it helps if you are going for a sequence or movie.

Practice on the evenings leading up to the eclipse. Don't wait to try it until the last night.

Thanks, Practice seems like an obvious piece of advice, but not something I had thought of. I need to learn how to intergrate IM3 with the 40d as well so some time under the stars over the next couple of nights is in the plan.
