I spent a little time photographing yesterday’s Solar Eclipse over Boulder, where the sun was 93% blocked by the moon. Enjoy these photos! I’m traveling for the next couple of days but thought I would send them out (I’m at the airport now).

This is the mostly eclipsed sun, when a few clouds went in front of the sun, giving it a slight discoloration:

This is toward the beginning of the eclipse when the moon was gradually covering the sun:

You can see sun spots toward the bottom of the sun, as the moon moves a bit closer:

Closer still:

This is approaching the maximum here in Boulder:

I took these image with a Canon 5D Mark III camera, using a 300 mm f/4 lens and a 2x extender (600 mm total at f/8). I used a tripod to hold the lens and used the image stabilizer built into the lens to avoid camera shake. Specs for the images: 1/160 second exposure, f/8, ISO 1600, 600 mm.

In order to not burn the camera or my eyes, I created a solar filter by tearing apart a pair of eclipse glasses; this is the same filter I built for the Venus transit in 2012. Learn how I made this build.

It should go without saying… don’t try this at home without a real solar filter.

Okay… now back to Website development and marketing!
