A couple of photographers I know, Charles and Carmelita, invited my boys and I over to view the transit of Venus across the face of the sun. A once in a lifetime opportunity. They are avid amateur astronomers, and have the gear to do it right. I was able to hold my iPhone up to the eyepiece of the telescope, and voila!
Another century from now, my boys might have a chance to see it again. Glad I got to see it now, since I won’t have that chance.
