In 1971, the mission of Apollo 14 flew to the Moon and landed Alan Shepard and Edgar Mitchell near Cone Crater in the Fra Mauro Highlands. Orbiting above the Moon was Stuart Roosa, the Command Module Pilot. Roosa had been a smoke jumper before becoming an Astronaut and in honor of that profession and their work, he carried a packet of seeds of several different types of trees. When they returned to Earth, the seeds were distributed to all the states and trees were grown from the seeds. The trees were planted at many different sites and the University of Arizona received one of the seedlings which was planted between the Lunar and Planetary Laboratory and the Flandrau Planetarium where it has been since before I arrived on campus. I have enjoyed watching it grow over the years.
The above image shows the Moon tree in late June 2014 as I was test driving a new lens for my Canon 70D. The new lens is a Sigma 18-250mm telephoto, in this case set at 18mm focal length. The exposure was 1/400 seconds at f/8, ISO 800.
This 2nd image shows the sign in front of the Moon tree and was taken from the exact same spot as the first image, showing the range in focal length of my new lens. This image was taken at 250mm focal length with an exposure of 1/320 seconds at f/8, ISO 800. It also shows the sharpness of the lens which appears quite good given its large range in focal length.
