Details:
In this desert twilight, the sky shifts from slate to peach above a black ridge line. On the right, a crescent moon sits low in the sky, 1.75 days past new. The left inset shows Kitt Peak, at 7,000 feet elevation, with the 4-meter Mayall Observatory, the second largest telescope n the world in the early 1970s, and on the far left of that inset, the McMath-Pierce Solar Telescope, at one time the largest solar observatory in the world. Kitt Peak is the only national observatory complex in the United States, with about 20 observatories on site, still producing state of the art science.
I took this photo from my home in Oro Valley, AZ and sights like this are a relatively common occurrence in our very clear desert sky’s. My straight line distance to Kitt Peak is 50 miles with the Moon positioned somewhat in the distant background. :-) As a sidebar note, the McMath-Pierce solar scope was used to train the Apollo astronauts for their lunar landing sites. The moon was projected as a 3 foot diameter object on the observing table from which all the Apollo astronauts could observe simultaneously. Most appropriate that this photo shares such wonderful Astronomy related images.
