This will be a short post – I just wanted to share my photo of Venus’s transit across the sun today. As I posted previously, it will be more than a century before this happens again. I didn’t plan well and almost couldn’t find eclipse glasses to watch the transit. Fortunately, I picked up a $2 pair at the local science museum. Yay!
To take this photo, I used my Canon 40D and a 70-200mm lens. I actually hand-held the flimsy eclipse glasses over the lens and then zoomed out as far as I could before the glasses vanished (probably about 170-180mm). I used the lowest ISO (100) and f-stop (f4) I could and then manually tested shutter speeds until I found the best one for exposure and avoiding hand/camera-shake blurring.
Here is Venus crossing the sun about 6:30pm.
