This is a Brunson Type 89 Rotating Base in superb condition. This is the earlier version of the base and differs from the current version in two important respects. The spacing of the two �wye� supports is slightly wider on the early base � 9.5 inches instead of the current 8.375 inches. The other feature is the captive upper clamping rings with spring-loaded pins. The clamps swing into place over the telescope tube and are held by small precision pins.

The support will work with most telescopes and collimators of 2.250� standard diameter. The mount has full 360 degree azimuth rotation which may be clamped at any point whereupon a fine adjustment may be carried out using a large milled knob. The carrier base has a standard 3.5 inch x 8 internal thread. Four milled heads are provided for precise leveling.

The base does have some paint loss on the upper surface of the support bar (see second photo), but is otherwise in near-mint condition.
