Bok Telescope, Infrared telescope at Kitt Peak National Observatory, Arizona.

The Bok Telescope is an optical and infrared instrument with a 2.3-meter primary mirror located at Kitt Peak in Arizona. The equipment can operate in multiple optical configurations to suit different astronomical observation needs.

The Bok Telescope is named after Bart Bok, director of Steward Observatory from 1966 to 1969 and a widely admired astronomer in Tucson. On 18 March 2007 Bruno Sicardy used it to observe Pluto occult a star in Sagittarius. In the 2010s it took g- and r-band images with the 90Prime imager as part of a survey preparing for the DESI instrument on the 4-m Mayall telescope.

The telescope is named after Bart Bok, Steward Observatory's director from 1966 to 1969 and a widely liked figure in Tucson. Its building has a long spiral staircase up to the telescope and a balcony known as "The Bok Walk".

The telescope runs all year except for an August summer shutdown, when maintenance is done during Arizona's monsoon season, roughly July through August. The building has a long spiral staircase up to the telescope and a balcony known as "The Bok Walk".

The instrument is equipped with the 90Prime imaging system, which provides an unusually wide field of view for sky photography. This component allows large sky regions to be captured in a single exposure.
