Totality! — click to enlarge


Totality from our location in Grand Teton National Park lasted about 1 minute and 50 seconds — we were about 10-15 miles north of the centerline.  Using my Canon 40D with 100-400 zoom lens at 400 mm, I programmed an automated sequence of exposures into Backyard EOS, varying from 1/250 @ f/8 ISO 100 to 1 sec @ f/5.6 ISO 800. I was able to capture 21 images. Extensive processing of 12 of those images in Photoshop resulted in this HDR composite, which not only shows the solar corona to about 3 solar radii, but also shows detail on the lunar surface (due to the phenomenon of “earthshine”).
