84% Annular Eclipse - What fun!

What fun to (indirectly!) watch the solar eclipse today. The image was not nearly as stunning as the photos I've seen of the full annular eclipse, such as the sunrise in China. Nevertheless, it was great fun. We went to Shoreline Park, in Mountain View, California where we set up a tripod with binoculars projecting onto white cardboard:


Around 6:20pm - To see the image better, we created a shadow on the cardboard by holding the binocular case above and behind the tripod.



Our friend, John, held the cardboard - and in this case, a visor to add  a shadow. You can see the binoculars taped to the tripod. what you may not notice is that the binoculars are BACKWARDS (a recommendation from a passing stranger; worked nicely!)



Around 6:30pm we had the maximum eclipse for our region, purported to be 84% according to the Exploratorium Museum.
Want to learn what an annular eclipse is all about? Check out the article published by the Exploratorium, one of my favorite science museums on the planet (well worth a visit next time you're in San Francisco!)

  1. "What fun" is right! I love it! Wish we could have seen it here, but those of us on the east coast were shut out altogether. I love your setup for the 3rd shot!

  2. Nice work - very inspiring for kids to see as well (not just us adults). Great science exploration motivator. Best wishes Jim.

  3. While it is understandable that you want your memories captured in both mediums, having both trying to shoot your event at the same time is a common cause of conflict on the wedding day.
