BRUNSON 89 Rotating Telescope Mounting Base
$300.00
BRUNSON 89 Rotating Telescope Mounting Base
The model 89 is a precision mounting base designed to accommodate almost all Brunson 2.25″ diameter alignment telescopes and collimators . The instrument is supported by two wyes which are 8.375 (212.7mm) on center, and are mounted to a channel-sectioned bar. The wyes provide stable support of the instrument barrel.
Precise rotation in a horizontal plane is controlled by the patented Brunson ball bearing spindle, similar to that of all Brunson transits. The mounting base has a standard 3.50″-8 internal thread for attachment to any compatible optical tooling stand. A fine motion tangent screw allows easy azimuth control, and incorporates a wobble pin for tension relief and a stable setup. Four large-headed leveling screws in nylon bushings make tilt adjustment easy.
Note: The original Brunson 89 had a wye spacing of 9.50″, but was modified for the somewhat smaller spacing of 8.375″ in order to fit all of the K+E design alignment telescopes.
MAY BE USED WITH:
271 Tilt Collimator
272-15 Multiple Target Collimator
2022 family, 2024 family, 2062, and C47280 Alignment Telescopes
