Stargazing at the Waterfront - 2016 July 09
Saturday was a supreme winter's day in Cape Town. The increased buzz at the Waterfront was evident even as we began to set up at our usual spot at the historic swinging bridge. The first four photos below show the eary rush and the clear blue sky. By the end of the evening, we had at least 1,622 eyes-at-eyepieces.

With a pinhole, a bit of planning, and a tape measure, you can determine the actual size of the Sun. Using the geometry of similar triangles, and the known distance to the Sun, the distance from the pinhole to the projected solar image is used to derive the diameter of the Sun. The pair of photos below show two Sun Measuring Teams, happy with their experimental results.
