Mounted to the telescope’s tube, a Boller and Chivens 6 inch finder telescope.
Mounted to the telescope’s mirror is a Boller and Chivens “X” and “Y” positioning prime focus guiding eye-piece assembly with slide-in 4″ by 5″ glass film plate holders and slide-in filter plate holders.This telescope is located at the Pine Mountain Observatory and has been reconfigured by DFM Engineering.

24-Inch (.61 meter) Telescope Specifications

All 16 inch telescopes had a Strain-Gauge motion control paddle. Tipping the front plate of the paddle in a desired travel direction, the paddle would give from a variable fine-drive motion to faster setting speeds. Simultaneously pushing down a control button on the back of the paddle, the telescope shifted into combinations of East-West Hour Angle and North-South Declination slew motion.

The Bok Telescope was named after the prolific astronomer and director of Steward Observatory from 1966–1969, Bart Bok, one of the most beloved astronomers in Tucson. The building itself features a very long spiral staircase leading to the telescope and a balcony called “The Bok Walk”. A sign titled “The Bok Walk” was instigated and installed on the inside of the door opening onto the outside balcony by Don Winans of Boller and Chivens during the installation of the 90-inch telescope. Dr. Bok had a ritual that before doing any observing of always going out on the domes outside balcony to investigating what the “seeing” conditions would be for his observing schedule that night. Dr. Bok and Don Winans became close friends when the Boller and Chivens 40-inch telescope was installed at Siding Springs, Australia.

The telescope was contracted as a joint venture of L & F Industries and Boller and Chivens in 1963. In 1964, it was assembled by personnel from both companies in L & F Industries’ new assembly building in Huntington Beach, California.

This telescope had the first completely redesigned mount, drive systems, and mirror support system.

Two 36 inch telescopes incorporated a basic design for Kitt Peak National Observatory (July 1967). All future Boller and Chivens off-axis telescopes 36 Inch and larger had a completely redesigned mount, drive systems, and mirror support system.

This telescope is no longer in use at the Lick Observatory. The Lick website states, “24-inch Photometric Telescope: This telescope appears to have been built between 1955 and 1961. It was a Boller and Chivens. In early 1995 it was dismantled and replaced by the KAIT.”

A recent comment left on this site has updated information about the location of this telescope: Hye-Sook Park at Livermore Lab was looking for a suitable scope for an experiment.  She refurbished it and sent it to Kitt Peak as Super-LOTIS. Here is the only live link I could find on the web:

This was a custom model 16 inch telescope modified to have electronic cables routed up thru the polar axle. These cables would service instruments mounted at the prime focus position on the back of the primary

mirror cell. The telescope had an optional motion control paddle as well as plug in receptacles under the position dials.
