Observing run at Kitt Peak National Observatory, near Tucson, Arizona, 2003 September 2-5

Fresno State students Dave Reynolds and John Prigge walk up to the 2.1-m (84-inch) telescope at Kitt Peak National Observatory.
Look at the Moon!

The 2.1-m telescope at Kitt Peak National Observatory was built in 1962. A comparable instrument would cost $5 million today.

Fresno State student Dave Reynolds is briefed on operating the 2.1-m telescope by KPNO staff associate Bill Gillespie.

Baboquivari Peak, here seen from Kitt Peak, is regarded as the center of the Universe by the Tohono O'odham tribe who live nearby. It is fitting that it is on a direct line of sight to the national observatory.

This is another view of the 2.1-m telescope. At the right is the 0.9-m Coudé Feed Telescope, used to gather starlight for the coude spectrograph in the 2.1-m dome, when the 2.1-m telescope is being used with another instrument.

The 1.2-m Calypso telescope, on Kitt Peak, was privately built by Edgar Smith, an amateur astronomer interested in high-resolution imaging of globular clusters. The last time a wealthy amateur used a comparable amount of his own money to build a state-of-the-art telescope primarily for science observations he intended to do himself was Percival Lowell, in 1894.
