Vixen Telescope Dual Speed Focuser

With the installation of the Vixen Dual Speed Focuser, the rack-and-pinion focusing equipment on your Vixen Telescope can be upgraded to provide finer focus adjustments. Allows dual-speed focusing with coarse and fine speed adjustments. The Dual Speed Focuser can be retrofitted to the rack and pinion focuser, by removing one of the focusing knobs attached to it. The Dual Speed Focuser allows 1/7th speed focusing and it can be attached on either side of the focusing shaft.
