An indispensable accessory, especially in astrophotography.
The reduction can be retrofitted on the following telescopes:

Cannot be used on old devices from the 90s with plastic focusing knobs - in these cases, it is also necessary to swap the focus spindle (please contact us for details).
Provide Finer Focus Adjustments
When installing 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.
