Transit of Venus - June 2012

Inside of the huge pinhole camera

Being a big fan of astronomy I of course was very ready and prepared for the last chance any of us had to see Venus come between us and the Sun yesterday afternoon. Well... I wasn't as ready as I had hoped for. About a month ago I made plans to buy solar filter film to place on the front end of my telescope, a camera adapter to connect my Canon to my Polaris, and hopes of grandeur for amazing photos that I could submit to Astronomers Without Borders to help them determine distances in our solar system. Did that happen? Ha! Nah! I slacked off. But I did get to work on a large pinhole camera where I could snap photos of the projected image of our sun within.

So I punched a small 1/4" hole in the center of one side for the "lens," a larger 77mm hole off-set from that for my DSLR's lens, lined the inside opposite side with white matte paper, the other walls with black gaffers tape to suck up any ambient light bouncing around, and the same gaffers tape on the outside to completely seal the box from any light leaks. Viola!

So I've got my huge pinhole camera ready for safely viewing the sun, camera ready to snap photos of Venus crossing the face of the sun for the last time we will ever see this rare event... and the outcome? Cloudy skies! Well, I guess I'll try again in 2117 when the next transit is. In the meantime I've got a very large pinhole camera that could fit any size film, even ultra large format film (above 8"X10").
